[PATCH] sbp2 (ieee1394) for lk2.5.44-bk3
This firewire mass storage driver is broken by the biosparam
changes. Small hack in patch below so it will compile in
2.5.44 (was set up anticipating 2.5.45 but would not have
compiled).
Doug Gilbert
<dougg@torque.net>
Changes:
- add SYNCHRONIZE_CACHE command support
- clean up module removal noise
- add some more parameters for driverfs
merges work from Patrick
Mansfield. There are now options to set:
- max_luns (default 2)
- scsi_level (default 3)
Now if multiple scsi_debug pseudo devices are selected
they will get these tuples (assuming "2" is the next
available host number):
2 0 0 0
2 0 0 1
2 0 1 0
2 0 1 1
2 0 2 0
...
2 0 7 1
3 0 0 0

<greg@kroah.com>
[PATCH] USB: audio fix up for missed debug code.
<ddstreet@ieee.org>
[PATCH] [patch] set interrupt interval in usbfs
This patch sets up the URB interval correctly when using interrupts via
usbfs. This is finally possible since the automagic resubmission is gone.
<Matt_Domsch@dell.com>
megaraid: avoid 64/32 division when calculating BIOS CHS translation
<jtyner@cs.ucr.edu>
[PATCH] USB vicam.c: minor fixes
This patch fixes some things that have failed to go in as part of other
patches that have been rejected. Namely, this adds the forgotten up call
in the read function, removes the usb_put_dev (since there is no
usb_get_dev), and also moves the allocation and freeing of the image and
frame buffers to the open and close calls only.
<jmorris@intercode.com.au>
[CRYPTO]: Cleanups based upon feedback from jgarzik.
- make crypto_cipher_flags() return u32 (this means it will return
the actual flags reliably, instead of being just a boolean op).
- simplify error path in crypto_init_flags().
<jmorris@intercode.com.au>
[CRYPTO]: Add crypto_alg_available interface.
<bart.de.schuymer@pandora.be>

[PATCH] PCI hotplug comment fixes
Fix comments about /sbin/hotplug; pci_insert_device does not call
/sbin/hotplug.
<scottm@somanetworks.com>
[PATCH] 2.5.45 CompactPCI driver patch 1/4
This is a patch 1 of 4 of my CompactPCI hotplug core and
drivers, consisting of the required core PCI changes.
The various arch file changes are to change pcibios_fixup_pbus_ranges to
from __init to __devinit, so that pci_setup_bridge can be safely exported
from drivers/pci/setup-bus.c.
<greg@kroah.com>
PCI: move EXPORT_SYMBOL for the pbus functions to the setup-bus.c file.
This fixes a linking error if setup-bus.c isn't compiled into the kernel.
<scottm@somanetworks.com>
[PATCH] 2.5.45 CompactPCI driver patch 2/4
This is patch 2 of 4 of my CompactPCI hotplug core and
drivers, consisting of the CompactPCI hotplug driver core.
It is basically a glue layer on top of the PCI hotplug core that exposes
an API roughly similiar in concept to the API implemented by MontaVista
from the PICMG 2.12 specification, minus all the Win32isms and cruft.
<scottm@somanetworks.com>
[PATCH] 2.5.45 CompactPCI driver patch 3/4
This is patch 3 of 4 of my CompactPCI hotplug core and
drivers, consisting of the Ziatech ZT5550 hotplug driver.
The hardware banging code in this driver started its life in the PICMG
2.12 driver code that MontaVista released at the end of 2001.
<scottm@somanetworks.com>
[PATCH] 2.5.45 CompactPCI driver patch 4/4
This is a patch 4 of 4 of my CompactPCI hotplug core and
drivers, consisting of the generic port I/O cPCI hotplug driver.
Let me know if the kernel parameter parsing code that's #ifndef MODULE is
objectionable. I spent quite a while today testing it, it seems reasonably
robust. Without it, this driver would only be useable as a module, which
I've not figured out how to do with the new kernel configuration stuff.
<greg@kroah.com>
[PATCH] PCI Hotplug: removed a compiler warning of a unused variable in the cpcihp_generic driver.
<greg@kroah.com>
[PATCH] PCI Hotplug: fix compiler warning.
<jung-ik.lee@intel.com>
[PATCH] Patch: 2.5.45 PCI Fixups for PCI HotPlug
The following patch changes function scopes only but fixes kernel dump on
Hot-Add of PCI bridge cards.
<t-kouchi@mvf.biglobe.ne.jp>
[PATCH] ACPI PCI hotplug updates
These are updates of the acpiphp driver for 2.5.
- change debug flag from 'acpiphp_debug' to 'debug' for insmod
- whitespace cleanup
- message cleanup
<dougg@torque.net>
Attached is an addition to the patches on this driver that
I've been posting recently. This one adds:
- slave_attach() and slave_detach()
- code clean up looking for a problem **
- more debug code allowing scanning cmd sequence to
be seen in the log (when opts=1)
** after several (never the first) sequences of modprobe/rmmod
on scsi_debug there is either:
- an oops during modprobe when driverfs tries to create a
directory
- or a WARN_ON() at drivers/base/bus.c:277 during rmmod
[examples attached]
I'm not sure whether the problem is in scsi_debug, the
scsi mid level or in the driverfs code. Grepping indicates
that not many people currently utilize per driver parameters
with driverfs (i.e. driver_create_file() and
driver_remove_file()).
<anton@samba.org>

<rmk@flint.arm.linux.org.uk>
[SERIAL] Fix up ARM serial drivers
This cset makes ARM serial drivers build.
<rmk@flint.arm.linux.org.uk>
[ARM] Fix typo in arch/arm/mm/Makefile
Typo prevented ARM926 cpu enabled builds from succeeding.
<hch@lst.de>
[PATCH] get rid of ->init in osst
Since osst is the last driver still implementing ->init and Willem said
he's gonna do a major update including a resync with st anyway I think
it's okay to put this hack in for now. Instead of ->init beeing
directly called from the midlayer osst_attach now calls in in the
beginning - it has an internal protection so that the initialization
will be called only one anyway.
<hch@lst.de>
[PATCH] proper scsi_devicelist handling
Factor out code calling methods of all device template on a scsi_device
out to three helper functions in scsi.c, make scsi_devicelist static to
it and add a r/w semaphore to protect it.
Make scsi_host_list and scsi_host_hn_list static to hosts.c and remove
the never used scsi_host_tmpl_list (we only add to it and remove from
it but never traverse it)
<davem@nuts.ninka.net>
[SPARC64]: Handle kernel integer divide by zero properly.
<hch@lst.de>
[PATCH] get rid of global arrays in sr
Similar cleanup to the recent sd patch: allocate the scsi_cd struct
in sd_attach instead of needing the global array and sd_init.
Tested with a DVD reader/CD write combination and ide-scsi.
<zaitcev@redhat.com>
[SPARC]: Update makefiles for current kbuild.
<zaitcev@redhat.com>
[SPARC]: Streamlined probing for Zilog.
<zaitcev@redhat.com>
[SPARC]: Cleanups and bug fixes.

<rth@dorothy.sfbay.redhat.com>
Zero UNIQUE on exec.
<jgarzik@redhat.com>
Alan snuck in an ugly bandaid into de2104x net driver...
add a #warning so it's not forgotten.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: initramfs updates
Use ld to link the cpio archive into the image, build was broken
due to requiring a recent version of objcopy before, plus assorted
cleanups:
o Don't include arch/$(ARCH)/Makefile, export the needed arch-specific
flags instead.
o Name the generated section consistently .init.ramfs everywhere.
<erik@aarg.net>
[PATCH] USB: added support for Palm Tungsten T devices to visor driver
<rth@dorothy.sfbay.redhat.com>
Merge bits from entry-rewrite tree:
* Whitespace cleanups in entry.S
* Pass in pt_regs by reference, not by fake value, to some entry points.
* Don't export wrusp.
<rth@dorothy.sfbay.redhat.com>
Fix single denorm -> double conversion.
Patch from George France <france@handhelds.org>.
<anton@samba.org>
ppc64: updates from Dave Engebretsen in 2.4
<rth@dorothy.sfbay.redhat.com>
More merging from entry-rewrite tree:
Implement sys_sethae, osf_getpriority, sys_getxuid, sys_getxgid, sys_getxpid,
sys_pipe, alpha_ni_syscall directly in assembly.
Bounce alpha_create_module, sys_ptrace through an assembly stub to pass
pt_regs by reference.
<rusty@rustcorp.com.au>
[PATCH] Initializer conversions for drivers/block
The old form of designated initializers are obsolete: we need to
replace them with the ISO C forms before 2.6. Gcc has always supported
both forms anyway.
<anton@samba.org>
ppc64: rework ppc64 hashtable management
<anton@samba.org>
ppc64: defconfig update
<hch@lst.de>
[PATCH] get rid of sg_init
Next step of my ->init removal series. sg does a few to much wierd
things with it's global array thay I prefer to leave it to Doug to
get rid of it (if he wants to), but this patch at least gets rid of
sg_init.
Move the register_chrdev to init_sg - open properly checks whether
the device exists so this doesn't cause any harm. Remove the initial
allocation of the device array - the resizing code in sg_attach will
properly take care of it when called the first time.
Tested with a DVD reader/CD writer combination and ide-scsi.
<davem@nuts.ninka.net>
[AF_KEY]: Convert to/from IPSEC_PROTO_ANY.

[SPARC64]: Add initramfs sections.
<davem@nuts.ninka.net>
[SPARC]: Add initramfs bits.
<davem@nuts.ninka.net>
[SCTP]: Convert to xfrm_policy_check.
<davem@nuts.ninka.net>
[TCP_IPV6]: Remove unused label discard_and_relse.
<davem@nuts.ninka.net>
[IPSEC]: Export xfrm_policy_list.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Fix up initramfs, adapt arch/alpha
Grrh, don't do last minute changes without retesting.
Adapt arch/alpha as well, other archs need to
o add LDFLAGS_BLOB to arch/$(ARCH)/Makefile
o add .init.ramfs to arch/$(ARCH)/vmlinux.lds.S
See arch/i386/{Makefile,vmlinux.lds.S} for guidance ;)

[PATCH] revamped machine check exception support.
- Split out from bluesmoke.c into per-vendor files (Me)

per-vendor bits CONFIG_ options, but thats probably overkill)
- Fixes Kconfig markup. (Roman Zippel)
- P4 can use non-fatal background checker too. (Venkatesh Pallipadi)
- Don't clear MCA status info in case of non-recoverable if
OS has failed in logging those, BIOS can still ahve a look at
that info. (Venkatesh)
- We can init bank 0 on P4 (Zwane Mwaikambo)
- Compile away to nothing if CONFIG_X86_MCE=n
- Various other cleaning (Me)
<rmk@flint.arm.linux.org.uk>
[ARM] Make ARM SCSI drivers build
2.5.46 appears to require drivers/scsi/scsi.h to be included before
drivers/scsi/hosts.h. Make this happen in the Acorn SCSI drivers.
<scott.feldman@intel.com>
e100 net driver: remove driver-isolated flag/lock.
Other locks already cover the areas in question, and additionally
this lock was held in areas where it should not have been, triggering
error messages in 2.5.x.
<hch@sgi.com>
[PATCH] fix intermezzo compile failure
Intermezzo has some strange, broken code trying to deal with extended
attributes and and ACLs. Fortunately the xattr code is hidden under
a config option that's never set, but the ACL code is enabled by
CONFIG_POSIX_ACL that's se by ext2/ext3 and jfs now. Change it to
#if 0 to get intermezzo compiling again.
<yokota@netlab.is.tsukuba.ac.jp>
[PATCH] NinjaSCSI-3R driver patch updated.
NinjaSCSI-3R PCMCIA SCSI host adapter driver updated for the latest
kernel tree.
<rmk@flint.arm.linux.org.uk>
[ARM] Fixes for 2.5.46
- Add LDFLAGS_BLOB definitions
- Tweak kernel_thread for better code
- Fix vmlinux-armv.lds.in to prevent ld complaining about the
architecture private flags.
(I'm not certain that the last item isn't a hole in some bug fix in
ld - this fix appears to work with every binutils I've found thus
far. However, if this suspected bug gets fixed, we're going to have
to rethink how we combine binary objects into ELF objects.)
<akpm@digeo.com>
[PATCH] `event' removal: core kernel
Patch from Manfred Spraul
f_version and i_version are used by filesystems to check if it can
reuse the f_pos position across readdir calls without validation.
Right now f_version and i_version are modified by
f_version = ++event;
i_version = ++event;
if (f_version != i_version) goto revalidate
and event is a global, exported variable.
But that's not needed,
f_version = 0;
i_version++;
if (f_version != i_version) goto revalidate
works too, without the ugly 'event' variable.
I got an ok from viro, and I had notified the fs maintainers, no
complaints either
- block_dev.c, block_llseek updates f_version to '++event'.
grep showed that no device driver uses f_version, this is dead
code copied from the default llseek implementation.
- the llseek implementations and get_empty_flip set f_version
to '++event'
This is not dead code, but
filp->f_version = 0
achieves the same effect:
f_version is used by the readdir() implementation of several
filesystems to skip the revalidation of f_pos at the beginning
of a readdir call: If llseek was not called and the filesystem
did not change since the last readdir call, then the value in
f_pos can be trusted.
The implementation (for example in ext2) is
inode->i_version = ++event;
in all operations that change a directory
At the beginning of file_operation->readdir():
if(inode->i_version != flip->f_version)
revalidate();
filp->f_version = inode->i_version;
There are other users of f_version, but none of them use the
default llseek implementation (e.g. fs/pipe.c)
<akpm@digeo.com>
[PATCH] `event' removal: ext2
Patch from Manfred Spraul
Use a local counter instead of the global 'event' variable for the
readdir() optimization.
Depends on patch-event-II
Background:
The only user of i_version and f_version in ext2 is
ext2_readdir(). As an optimization, ext2 performs the
validation of the start position for readdir() only if
flip->f_version != inode->i_version.
If there was no llseek and no directory change since the
last readdir() call, then f_pos can be trusted.
f_version is set to 0 in get_empty_flip and during llseek.
Right now, i_version set to ++event during ext2_read_inode
and commit_chunk, i.e. at inode creation and if a directory
is changed.
Initializing i_version to 1, and updating with i_version++
achieves the same effect, without the need of a global variable.
Global uniqueness is not required, there are no other uses
of [if]_version in ext2.
Change relative to the patch you have right now:
i_version is initialized to 1 instead of 0. For ext2 it's doesn't
matter [there is always a valid 'len' value at the beginning of a
directory data block], but it's cleaner.
<akpm@digeo.com>
[PATCH] `event' removal: other filesystems
Patch from Manfred Spraul
Several filesystems compare f_version and i_version to validate
directory positions in readdir(): The directory position is revalidated
if i_version is not equal f_version. Operations that could invalidate
the cached position set i_version or f_version to '++event', event is a
global variable. Global uniqueness is not needed, 'i_version++' and
'f_version=0' is sufficient to guarantee that the next readdir() will
revalidate the directory position, and that avoids the need for an ugly
global variable.
The attached patch converts all filesystems except ext2, which was
converted with a seperate patch.
<akpm@digeo.com>
[PATCH] `event' removal: kill it
Final act, from Manfred:
The attached patch removes 'event' entirely from the kernel: it's not
used anymore.
All event users [vfat dentry revalidation; ext2/3 inode generation;
readdir() file position revalidation in several filesystems] were
converted to local counters.
<akpm@digeo.com>
[PATCH] fix mod_timer() race
If two CPUs run mod_timer against the same not-pending timer then they
have no locking relationship. They can both see the timer as
not-pending and they both add the timer to their cpu-local list. The
CPU which gets there second corrupts the first CPU's lists.
This was causing Dave Hansen's 8-way to oops after a couple of minutes
of specweb testing.
I believe that to fix this we need locking which is associated with the
timer itself. The easy fix is hashed spinlocking based on the timer's
address. The hard fix is a lock inside the timer itself.
It is hard because init_timer() becomes compulsory, to initialise that
spinlock. An unknown number of code paths in the kernel just wipe the
timer to all-zeroes and start using it.
I chose the hard way - it is cleaner and more idiomatic. The patch
also adds a "magic number" to the timer so we can detect when a timer
was not correctly initialised. A warning and stack backtrace is
generated and the timer is fixed up. After 16 such warnings the
warning mechanism shuts itself up until a reboot.
It took six patches to my kernel to stop the warnings from coming out.
The uninitialised timers are extremely easy to find and fix. But it
will take some time to weed them all out. Maybe we should go for
the hashed locking...
Note that the new timer->lock means that we can clean up some awkward
"oh we raced, let's try again" code in timer.c. But to do that we'd
also need to take timer->lock in the commonly-called del_timer(), so I
left it as-is.
The lock is not needed in add_timer() because concurrent
add_timer()/add_timer() and concurrent add_timer()/mod_timer() are
illegal.
<akpm@digeo.com>
[PATCH] timers: initialisers
Add some infrastructure for statically initialising timers,
use that in workqueues.

[PATCH] timers: scsi
The patches which I needed to avoid the warnings with my build.

[PATCH] fix slab allocator for non zero boot cpu
The slab allocator doesnt initialise ->array for all cpus. This means
we fail to boot on a machine with boot cpu != 0. I was testing current
2.5 BK.

[PATCH] usbtest, Kconfig and misc
Minor patches:
- resend of the Config.in patch, updated to Kconfig,
plus makes 'usbtest' modular when usb is;
- hmm, "usbfs" isn't locking here. protect. fix
is basically from martin: add/use a semaphore.
- that one-liner to make sure get_configuration is
called correctly (with funkier test firmware).
- new 'realworld' module param can be used to turn
off the real-world accomodations and be stricter
about what device failures make ch9 tests fail.

[PATCH] ohci-hcd, remove oops and...
Two changes, one big one not:
- check before traversing a null pointer, removing oops
- always do bandwidth checks, no point in allowing overcommit
That oops possibility has been there for a bit over two months,
but something changed recently which made me see it. Maybe
sme other folk have seen this one too (in ed_deschedule).

[PATCH] USB storage: use the new transfer_buf() routine
This patch switches from using usb_stor_bulk_msg() to
usb_stor_bulk_transfer_buf(), which includes a great deal more logic. This
allows for elimination of all sorts of duplicate code (clearing STALLs,
etc.).
This also eliminates the (now) redundant functions from the ISD-200 driver.

[PATCH] allow registering individual HBAs
Yes, this is the patch every maintainer of a modern HBA waited for the
last years </shameless plug>.
With all my recent changes there's no more reason to call scsi_register_host
except for the intialization it performs to every host found in
scsi_register. But a driver can aswell do that at the end of it's
per-HBA detection routine (i.e. in ->probe for a modern PCI driver), so
export that code as scsi_add_host to drivers. Do the same for the
release path (scsi_remove_host). Such a new-style driver needs neither
->detect or ->release and is in theory hotplug-capable (well, once all
the races in the scsi midlayer are fixed..)

[PATCH] scsi device template cleanups
Now that .init isn't implement anymore we can get rid of it and

* remove .dev_noticed, only midlayer user is gone together with
.init. remaining instance now driver-private
* remove .nr_dev and .dev_max - they're purely driver internal
and at least in sd and sr they'll be completly gone very soon.

[PATCH] `i_version' initialization fix
Ahm.
No. It must be i_version = 1
Otherwise there is a trivial bug:
mkdir("dir");
<force the directory out of dcache>
dir = open("dir");
lseek(dir,1,SEEK_SET);
readdir();
lseek sets f_version to 0, and readdir() trusts f_pos, because i_version
is 0, too. This applies to all filesystems.
The ext2 patch already sets i_version to 1.

[PATCH] [PATCH] 2.5.44 sa-1111 ohci hcd
Dereferencing hcd.pdev will always oops with SA-1111. It has to be
treated as a cookie, not a pointer in any common OHCI HCD code.
Apparently we need a clean way to go from struct device * to struct
ohci_hcd *. I added dev_to_ohci that does the obvious thing and added
separate implementations for PCI and SA-1111. Two implementations is
ugly but I didn't think it wise (for me) to hack on the PCI/driverfs
interface, so I just cut & paste the old code.
Two patches. The first is a diff from linux-2.5.44 and
linux-2.5.44-rmk1. It is from rmk and adds a struct device pointer to
ohci_hcd. The second depends on the first and contains my changes to
clean up to the pdev oops problems. (Some fuzz may occur as I have
ohci-1024 applied.)
With these changes, SA111 OHCI-HC/HCD is showing some signs of life on
linux-2.5.44-rmk1. usb-storage is currentl blowing chunks, but I think
I saw some patches go by against 2.5.44 that I haven't yet tried.

[MTD] mtdblock devices are called mtdblock%d not mtd%d
<jgarzik@redhat.com>
Remove performance barrier in i810_rng char driver.
In order to conserve CPU, the read(2) syscall would schedule_timeout
unconditionally. This also crippled speed, and was a bad design
decision. This cset merges the updated read(2) logic of the sister
driver amd768_rng from Alan, which schedules only when it needs to.
On my test system, by one microbenmark, read(2) output jumped
from 0.08 kbit/s to "what Intel expects" of 20 kbit/s.
End users may notice a significant decrease in idle time after
this change (and a correspondingly large increase in /dev/hwrng user
speed), if /dev/hwrng is used to its maximum capacity.

[PATCH] thread-aware coredumps, 2.5.43-C3
This is the second iteration of thread-aware coredumps.
Changes:
- Ulrich Drepper has reviewed the data structures and checked actual
coredumps via readelf - everything looks fine and according to the spec.
- a serious bug has been fixed in the thread-state dumping code - it was
still based on the 2.4 assumption that the task struct points to the
kernel stack - it's task->thread_info in 2.5. This bug caused bogus
register info to be filled in for threads.
- properly wait for all threads that share the same MM to serialize with
the coredumping thread. This is CLONE_VM based, not tied to
CLONE_THREAD and/or signal semantics, ie. old-style (or different-style)
threaded apps will be properly stopped as well.
The locking might look a bit complex, but i wanted to keep the
__exit_mm() overhead as low as possible. It's not quite trivial to get
these bits right, because 'sharing the MM' is detached from signals
semantics, so we cannot rely on broadcast-kill catching all threads. So
zap_threads() iterates through every thread and zaps those which were
left out. (There's a minimal race left in where a newly forked child
might escape the attention of zap_threads() - this race is fixed by the
OOM fixes in the mmap-speedup patch.)
- fill_psinfo() is now called with the thread group leader, for the
coredump to get 'process' state.
- initialize the elf_thread_status structure with zeroes.
the IA64 ELF bits are not included, yet, to reduce complexity of the
patch. The patch has been tested on x86 UP and SMP.

[PATCH] Make ->readpages palatable to NFS
The following patch makes the ->readpages() address_space_operation
take a struct file argument just like ->readpage().
<trond.myklebust@fys.uio.no>
[PATCH] Convert NFS client to use ->readpages()
- Add the library function read_cache_pages(), which is used in a
similar fashion to the single page 'read_cache_page()'. It hides
the details of the LRU cache etc. from a filesystem that wants to
to populate an address space with a list of pages.
- Fix NFS so that readahead uses the ->readpages() interface. Means
that we can immediately schedule an RPC call in order to complete
the I/O, rather than relying on somebody later triggering it by
calling lock_page() (and hence sync_page()). The sync_page()
method is race-prone, since the waiting page may try to call it
before we've finished initializing the 'struct nfs_page'.
- Clear out nfs_sync_page(), the nfs_inode->read list, and
friends. When the I/O completion gets scheduled in ->readpage(),
->readpages(), they have no reason to exist.

[PATCH] fix 2.5 scsi queue depth setting
This patch fixes queue depth setting of scsi devices.
This is done by pairing shost->slave_attach() calls with
a scsi_build_commandblocks in the new scsi_slave_attach.
This is a patch aginst linux-scsi.bkbits.net/scsi-for-linus-2.5 after
applying the last posted hch version of the "Eliminate scsi_host_tmpl_list"
patch, it still applies with offset to the current scsi-for-linus-2.5.
It also:
Will properly call shost->slave_attach after a scsi_unregister_device()
followed by a scsi_register_device() - as could happen if you were able to
rmmod all upper level drivers and then insmod any of them back (only
possible when not booted on scsi).
Checks for scsi_build_commandblocks() allocation failures.
Sets queue depth even if shost->slave_attach() does not call
scsi_adjust_queue_depth.
Removes the use of revoke (no drivers are setting it, it was only
call via the proc scsi remove-single-device interface).
There are at least two problems with sysfs and scsi (one in sysfs, one in
scsi, I'll try and post more soon ...) so I could not completey test rmmod
of an adapter or upper level driver without leading to an oops or shutdown
hang.

<lord@sgi.com>
[XFS] Contributed fix from ASANO Masahiro <masano@tnes.nec.co.jp>. In calculating
the layout of a log record for a buffer, the linux code deals with buffers
which are not contiguous in memory - this only applies to an inode buffer.
This adds one more fragmentation case to the code, and a line was missing
from this. The end result would be the logging of too much data if this
was not the last component of the buffer.
The code was definitely wrong, but I think the chances of hitting this were
pretty slim, and the resulting error would only matter if there was a
crash shortly afterward.

[PATCH] md: Misc little raid fixes
Roughly in order of patch:
1/ xor.h is never needed in md.c
2/ set sb_loaded when we 'sync' mddev to rdev as well as when we load
sb into rdev from disk.
2/ due to lifetime changes, active count can be 2 when we stop array
3/ due to lifetime changes, we need to explicitly clear the ->pers when we
stop an array
4/ autostart can only work for 0.90.0 superblocks.
None others would be silly enough to store device numbers for
all devices in the superblock...
5/ we had lost the setting of 'sb' when auto-starting an array.
6/ Code currently calls export_rdev(start_rdev) when
IS_ERR(start_rdev), which causes an oops.
7/ /proc/mdstat contents error:
code does not take into account that delayed
resyncs can wait with curr_resync = 1 or 2.
8/ There is a premature "return NOTIFY_DONE", that possibly was in
for debugging once...

[PATCH] md: Fix assorted raid1 problems.
From Angus Sawyer <angus.sawyer@dsl.pipex.com>:
1. Null pointer dereference in end_sync_read
r1_bio->read_disk is not initialised correctly in sync_request .
this is used in end_sync_read to reference the structure
conf->mirror[read_disk].rdev which with one disk missing is NULL.
2. Null pointer dereference in mempool_free()
This is a race between close_sync() conf->r1_bufpool =3D NULL and put_buf()
mempool_free().
bio completion -> resume_device -> put_buf -> mempool_free(r1_bufpool)
|
[ wakeup]
|
close_sync() -> r1_bufpool = NULL;
The patch attached reorders the mempool_free before the barrier is released
and merges resume_device() into put_buf(), (they are only used together).
Otherwise I have kept the locking and wakeups identical to the existing code.
(maybe this could be streamlined)
3. BUG() at close_sync() if (waitqueue_active(&conf->wait_resume).
This occurs with and without the patch for (2).
I think this is a false BUG(). From what I understand of the device barrier
code, there is nothing wrong with make_request() waiting on wait_resume when
this test is made. Therefore I have removed it (the wait_idle test is still
correct).
4. raid1 tries to start a resync if there is only one working drive,
which is pretty pointless, and noisy. We notice that special case and
avoid the resync.
<neilb@cse.unsw.edu.au>
[PATCH] md: Fix bug in raid5
When analysing a stripe in handle_stripe we set bits
R5_Wantread or R5_Wantwrite
to indicate if a read or write is needed. We don't actually schedule the
IO immediately as this is done under a spinlock (sh->lock) and
generic_make_request can block. Instead we check these bits after
the lock has been lifted and then schedule the IO.
But once the lock has been lifted we aren't safe against multiple
access, and it is possible that the IO will be scheduled never, or twice.
So, we use test_and_clear to check and potentially schedule the IO.
This wasn't a problem in 2.4 because the equivalent information was
stored on the stack instead of in the stripe.
We also make sure bi_io_vec[0] has correct values as a previous
call to generic_make_request may have changed them.
<neilb@cse.unsw.edu.au>
[PATCH] md: Fix another two bug in raid5
A partial block write over a block on a failed device
would need to pre-read that block, which means pre-read all
blocks in stripe and generate that block. But the generate-block
code never checked for this possibility, so it wouldn't happen.

[PATCH] kNFSd: Use ->sendpage to send nfsd (and lockd) replies.
From Hirokazu Takahashi <taka@valinux.co.jp>
As all rpc server replies are now in well defined pages,
we can use ->sendpage to send these replies, and so
make use for zero-copy transmit on network cards that
support it.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Support zero-copy read for NFSD
From Hirokazu Takahashi <taka@valinux.co.jp>
This patch changes read and readdir in nfsd.
read:
If the file supports readpage, we use it to collect pages out of the page
cache and to attache them directly to the outgoing nfs reply.
The reduces the number of copies by one, and if the filesystem/device
driver didn't copy the data, and if the network card can support not copying
the data, then you get zero-copy reads.
readdir:
A separate page is used for stoing the readdir response so that a fill
PAGE_SIZE bytes of reply can be supported.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Make sure final xdr_buf.len is correct on server reply
rq_res->len was not always updated properly.
It is only needed in the sendto routine, so we calculate
it just before that is called, and don't bother
updating it anywhere else.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Convert readlink to use a separate page for returning symlink contents.
This allows NFSv3 to manage 4096byte symlinks.
Also remove now-unused svcbuf_reserver function.
This was used to reserve space in output buffer
for 'data', but now this is stored in separate page.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd: Make sure svc_process releases response even on error.
If a rpc operation indicates that response should
be dropped (e.g. kmalloc failure) we must still
call pc_release to release anything it may have allocated.
<davidel@xmailserver.org>

[PATCH] Update macserial driver
This updates the macserial driver in 2.5 so it compiles and works. The
main changes are to use schedule_work instead of task queues and BHs.
The patch also removes the wait_key method.
I know we need to change macserial to use the new serial
infrastructure. I'm posting this patch in case it is useful to anyone
trying to compile up a kernel for a powermac at the moment.
<paulus@samba.org>
[PATCH] Update powermac IDE driver
This updates the powermac IDE driver in 2.5 so it uses the 2.5 kernel
interfaces and types rather than the 2.4 ones. It also makes it use
blk_rq_map_sg rather than its own code to set up scatter/gather lists in
pmac_ide_build_sglist, and makes it use ide_lock instead of
io_request_lock.

<paulus@samba.org>
PPC32: More sensible arrangement of the sections in vmlinux.lds.S.
This moves the sections which are read-only (e.g. exception table,
kallsyms data) to go before the read/write data section, and the

initramfs section.

[PATCH] too many setattr calls from VFS layer
New code in 2.5 VFS layer invokes notify_change to clear the suid and
sgid bits for every write request. notify_change needs to optimize out

systems, an on-the-wire SETATTR request is generated for every ->setattr
call, resulting in unnecessary latency for NFS writes.

The hugetlb page support in 2.5.46 is broken (Don't know if this is the

Clean up vfs_readv/writev() interface and avoid code duplication.
Make kNFSd use the cleaned-up interfaces, and disable the code that
accesses the low-level readpage() function of the exported filesystem
(not allowed - many filesystems need extra setup, which is why we have
a separate ->sendpage() routine for that).

ppc64: merge some ioctl32.c changes from sparc64
<kuznet@ms2.inr.ac.ru>
[IPSEC] More work.
1. Expiration of SAs. Some missing updates of counters.
Question: very strange, rfc defines use_time as time of the first use
of SA. But kame setkey refers to this as lastuse.
2. Bug fixes for tunnel mode and forwarding.
3. Fix bugs in per-socket policy: policy entries do not leak but are destroyed,
when socket is closed, and are cloned on children of listening sockets.
4. Implemented use policy: i.e. use ipsec if a SA is available,
ignore if it is not.
5. Added sysctl to disable in/out policy on some devices.
It is set on loopback by default.
6. Remove resolved reference from template. It is not used,
but pollutes code.
7. Added all the SASTATEs, now they make sense.

[PATCH] let binfmt_misc optionally preserve argv[1]
This makes it possible for binfmt_misc to optionally preserve the

which are invoked via binfmt_misc. I had brought up this patch a while
ago (see URL below) and there was no negative feedback (OK, there was no
feedback at all... ;-).
The patch is trivial and the new behavior is triggered only if the
letter "P" (for "preserve") is appended to the binfmt_misc registration
string, so it shold be completely safe.

only has 40 lines defined, instead of 41. This results in no sound

added the missing line, which is present in the OSS emu10k1 driver.

[PATCH] Add nfs_writepages & backing_dev...
The following patch adds a simple ->writepages method that interprets
the extra information passed down in Andrew's writeback_control
structure, and translates it into nfs-speak.
It also adds a backing_dev_info structure that scales the readahead in
terms of the rsize. Maximum readahead is still 128k if you use 32k
rsize, but it is scaled down to 4k if you use 1k rsize.
<trond.myklebust@fys.uio.no>
[PATCH] Make nfs_find_request() scale
nfs_find_request() needs to be called every time we schedule a write
on the page cache. Currently it is implemented as a linked list which
needs to be traversed completely in the case where we don't already
have a pending write request on the page in question.
The following patch adopts the new radix tree, as is already used in
the page cache. Performance change is more or less negligeable with
the current hard limit of 256 outstanding write requests per mount.
However when I remove this limit then the old nfs_find_request()
actually results in a 50% reduction in speed on my benchmark test
(iozone with 4 threads each writing a 512Mb file on a 512Mb Linux
client against a Solaris server on 100Mbit switched net). With this
patch, the result for the same benchmark is a 50% increase in speed.

[PATCH] soft and hard barriers
Right now we have one type of barrier in the block layer, and that is
used mainly for making sure that the io scheduler doesn't reorder
requests when we don't want it to. We also need a flag to tell the io
scheduler and low level queue that this is a barrier. So basically two
needs:
o software barrier, prevents the io scheduler from reordering
o hardware barrier, driver must prevent drive from reordering
So this patch gets rid of REQ_BARRIER and instead adds REQ_SOFTBARRIER
and REQ_HARDBARRIER.

[PATCH] Update ADB drivers in 2.5
This updates the ADB driver and the three low-level ADB bus adaptor
drivers used on powermacs. The files affected are all in
drivers/macintosh; they are adb.c, macio-adb.c, via-cuda.c and
via-pmu.c.
The main changes in this patch are:
- Remove the use of global cli/sti and replace them with local cli/sti,
spinlocks and semaphores as appropriate.
- Use DECLARE_WORK/schedule_work instead of tq_struct/schedule_task.
- Improvements to the PMU interrupt handling and sleep/wakeup code.

all in drivers/macintosh. First, the patch removes the old macintosh
ADB keyboard driver and the macintosh keymap file, which are no longer
used now that we use the input layer and the adbhid.c driver. Secondly,
it removes the drivers/macintosh/rtc.c driver, which was only ever used
on PPC, and which is obsolete now that we use the drivers/char/genrtc.c
driver instead.

[PATCH] slabify the sunrpc layer
In order to better cope with low memory conditions, add slabs for
struct rpc_task and 'small' RPC buffers of <= 2k. Protect these using
mempools.
The only case where we appear to use buffers of > 2k is when
symlinking, and is due to the fact that the path can be up to 4k in
length. For the moment, we just use kmalloc(), but it may be worth it
some time in the near future to convert nfs_symlink() to use pages.

[PATCH] Lift the 256 outstanding NFS read/write request limit.
Given the previous set of patches that integrate NFS with the VM +
pdflush memory control, and add mechanisms to cope with low memory
conditions, the time is now ripe to rip out the 256 outstanding
request limit, as well as the associated LRU list in the superblock,
and the nfs_flushd daemon.
The following patch offers a 30% speed increase on my test setup with
512MB of core memory (iozone using 4 threads each writing a 512MB file
over 100Mbit to a Solaris server). Setting mem=64m, I still see a 2-3%
speed increase.

[PATCH] do_nmi needs irq_enter/irq_exit lovin...
Use new "nmi_enter/exit()" which acts the same as the regular irq
entries (increases the preempt count appropriately), but doesn't try to
start processing softirqs on nmi exit (it just decreases the count).

[PATCH] enhance ->sendfile(), allowing kNFSd to use it
I enhanced the sendfile method so that we could pass a proper actor to
it (which exposes the full power of the internal implementation).
Now knfsd calls the sendfile vector rather than depending on a
readpage() that hasn't been set up fully.

[PATCH] NFS coherency fix
DOH!!! Somebody clone me a replacement brain: I must have burnt
another fuse. It turns out the new readpages was evading our
read/write serialization.
This broke things like 'ld' over NFS, which rewrites chunks of
files it has already written.

[PATCH] Fix readv/writev return value
A patch from Janet Morgan <janetmor@us.ibm.com>
If you feed an iovec with a bad address not at the zeroeth segment into
readv or writev, it returns the wrong value.
iovec 1: base is 8050b20 len is 64
iovec 2: base is ffffffff len is 64
iovec 3: base is 8050ba0 len is 64
The writev should return 64 bytes but is returning 128
This is because we've added the new segment's length into `count'
before running access_ok().
The patch changes it to fix that up on the slow path, if access_ok() fails.

[PATCH] SMP iowait stats
Patch from William Lee Irwin III <wli@holomorphy.com>
Idle time accounting is disturbed by the iowait statistics, for several
reasons:
(1) iowait time is not subdivided among cpus.
The only way the distinction between idle time subtracted from
cpus (in order to be accounted as iowait) can be made is by
summing counters for a total and dividing the individual tick
counters by the proportions. Any tick type resolution which is
not properly per-cpu breaks this, meaning that cpus which are
entirely idle, when any iowait is present on the system, will
have all idle ticks accounted to iowait instead of true idle time.
(2) kstat_read_proc() misreports iowait time
The idle tick counter is passed twice to the sprintf(), once
in the idle tick position, and once in the iowait tick position.
(3) performance enhancement
The O(1) scheduler was very carefully constructed to perform
accesses only to localized cachelines whenever possible. The
global counter violates one of its core design principles,
and the localization of "most" accesses is in greater harmony
with its overall design and provides (at the very least) a
qualitative performance improvement wrt. cache.
The method of correcting this is simple: embed an atomic iowait counter
in the runqueues, find the runqueue being manipulated in io_schedule(),
increment its atomic counter prior to schedule(), and decrement it
after returning from schedule(), which is guaranteed to be the same one,
as the counter incremented is tracked as a variable local to the procedure.
Then simply sum to obtain a global iowait statistic.
(Atomicity is required as the post-wait decrement may occur on a different
cpu from the one owning the counter.)
io_schedule() and io_schedule_timeout() are moved to sched.c as they must
access the runqueues, which are private to sched.c, and nr_iowait() is
created in order to export the sum of all runqueues' nr_iowait().

[PATCH] hugetlb: fix zap_hugetlb_resources()
Patch from William Lee Irwin III <wli@holomorphy.com>
This patch eliminates zap_hugetlb_resources, along with its usages.
This actually fixes bugs, as zap_hugetlb_resources was itself buggy.

[PATCH] buffer_head refcounting fixes and cleanup
There was some strange code in the __getblk()/__find_get_block()/
__bread() area which was performimg multiple bh_lru_install() calls as
well as multiple touch_buffer() calls.
Fix all that up. We only need to run bh_lru_install() and
touch_buffer() in __find_get_block(). Because if the block wasn't
found, __getblk() will create it and will re-run __find_get_block().
Also document a few things and make a couple of internal symbols static
to buffer.c
Also, don't run __find_get_block() from within
unmap_underlying_metadata(). We hardly expect to find that block
inside the LRU. And we hardly expect to use it as metadata in the near
future so there's no point in letting it evict another buffer if we
found it. So just go straight into the pagecache lookup for
unmap_underlying_metadata().
<akpm@digeo.com>
[PATCH] fix page alloc/free accounting
We're currently incrementing /proc/vmstat:pgalloc in front of the
per-cpu page queues, and incrementing /proc/vmstat:pgfree behind the
per-cpu queues. So they get out of whack.
Change it so that we increment the counters each time someone requests
a page. ie: they're both in front of the queues.
Also, remove a duplicated prep_new_page() call and as a consequence,
drop the whole additional list walk in rmqueue_bulk().

[PATCH] remove duplicated disk statistics
This patch will break some userspace monitoring apps in the name of
having sane disk statistics in 2.6.x.
Patch from Rick Lindsley <ricklind@us.ibm.com>
In 2.5.46, there are now disk statistics being collected twice: once
for gendisk/hd_struct, and once for dkstat. They are collecting the
same thing. This patch removes dkstat, which also had the disadvantage
of being limited by DK_MAX_MAJOR and DK_MAX_DISK. (Those #defines are
removed too.)
In addition, this patch removes disk statistics from /proc/stat since
they are now available via sysfs and there seems to have been a general
preference in previous discussions to "clean up" /proc/stat. Too many
disks being reported in /proc/stat also caused buffer overflows when
trying to print out the data.
The code in led.c from the parisc architecture has not apparently been
recompiled under recent versions of 2.5, since it references
kstat.dk_drive which doesn't exist in later versions. Accordingly,
I've added an #ifdef 0 and a comment to that code so that it may at
least compile, albeit without one feature -- a step up from its state
now. If it is preferable to keep the broken code in, that patch may
easily be excised from below.
