Summary of changes from v2.5.47 to v2.5.48
============================================
<vojtech@suse.cz>
Rescan a serio port in serio.c only when a character comes from it
only in case it's a valid character (correct parity, no timeout).
<rmk@arm.linux.org.uk>
Here's a patch that makes the RiscPC input bits work in 2.5:
- Call the RiscPC mouse "CONFIG_MOUSE_RISCPC" not "CONFIG_MOUSE_ACORN"
- Remember the last state of the buttons so we're not continuously
reporting this to the core input subsystem.
- Correct mapping of bits to buttons
- Correct button sense (1 = released)
- Always pass a dev_id when requesting an IRQ. Required for SA_SHIRQ
shared interrupts.
- Merge ARM keyboard controller config options
- General update for rpckbd.c
<kronos@kronoz.cjb.net>
I found a missing '\n' in serio.c:118. This prevents the next printk to
be interpreted correctly.
<jdike@uml.karaya.com>
A bunch of miscellaneous changes - mostly fixes from 2.4 and updates
to 2.5.43.
Added some Makefile fixes so the build works.
Brought the xterm not hanging fix from 2.4.
Updated the signal code from 2.4.
Fixed port_interrupt to not allocate IRQs.
The idle threads for the secondary processors are now killed off
on shutdown.
Some rwlock symbols are exported.
Added a system call entry for lookup_dcookie.
<jdike@uml.karaya.com>
A number of small fixes.
The port and xterm drivers handle -EAGAIN from os_rcv_fd gracefully,
fixing a crash in the xterm driver.
The ubd driver handles devfs_register failures better.
More symbols were exported.
<vojtech@suse.cz>
Add Logitech Wheel Mouse to the list of Logitech mice
that have a wheel in mousedev.c
<jdike@uml.karaya.com>
The block driver supports partitions again.
Removed an unused field from cpu_tasks.
<vojtech@suse.cz>
atkbd.c: Only issue the set LED command during probe when absolutely needed.
<jdike@uml.karaya.com>
Merged the 2.5.44 ubd driver changes.
<jdike@uml.karaya.com>
Updated to work as 2.5.44.
<dwmw2@infradead.org>
psmouse.c: First check for a Synaptics touchpad, other probes confuse
it enough to disable the trackpoint.
<vojtech@suse.cz>
Remove dead logibusmouse.h.
<vojtech@suse.cz>
hid-input.c: Back out a (wrong) find_next_zero_bit() patch from Arnaldo Carvalho de Melo.
<vojtech@suse.cz>
Fix open counting in usbkbd.c and usbmouse.c in case the irq urb
submit fails. Bug spotted by Thiemo Seufer.
<geert@linux-m68k.org>
Fix dyslexia in Amiga keyboard driver
<jejb@mulgrave.(none)>
[PATCH] add request prep functions to SCSI
This patch adds request prep functions to the mid-layer. At the moment, its a single request prep function for all of SCSI. I'v+
e altered the logic in scsi_request_fn so that we now do early preparation (this should improve throughput slightly in the untagged +
case with only a single command block).
The prep function also cannot drop the queue lock, so the calling assumptions for scsi_init_io and the upper layer driver init_co+
mmands have changed to be that the lock is now held and they cannot drop it. I think this means that we have no callers of scsi_ini+
t_io that aren't atomic, so perhaps I can just take the if out.
I've hammered this in my usual set up, but other testers would be welcome.

<hch@lst.de>
[PATCH] get rid of ->detect for upper layer drivers
Okay, we're finally at the point where ->detect has become entirely
superflous. In sd, sr and st it does nothing but return different
values that are ignored anyway, in sg it increments a variable
that is never read (and thus removed in this patch aswell), only
in osst it increments a variable that is actually checked for beeing
non-zero. But if it was zero we'd never reached that place anyway
(same check in the beginning of osst_detect and osst_attach).
This make the upper layer interface a lot nicer and avoids the
race condition where a device is remove between detect and attach
(which currently wouldn't matter anyway as we aren't doing anything
in detect anymore)
<agrover@groveronline.com>
ACPI: Interpreter update to fix mutex wait problem
This changes the timeout param around the interpreter to a u16, so that
ACPI_WAIT_FOREVER is equivalent to 0xFFFF, the value ASL expects to
mean "wait forever".
<agrover@groveronline.com>
ACPI: bus.c needed device.h included

Kconfig help text.
<varenet@parisc-linux.org>
Remove unused variable
This fixes a compiler warning.
<hch@lst.de>
[PATCH] remove some dead declarations from the scsi headers
<dougg@torque.net>
scsi_debug 1.64 , remove detect(), "hotplug" hosts
This patch is against lk 2.5.46-bk3 which includes
Christoph's work removing the requirement for
detect() functions in LLDDs. He sent me an example
for scsi_debug which I have built on with this patch.
As threatened, this version includes a "scsi_debug_add_host"
parameter. At kernel or module load time this is an absolute
number (0..127 are allowable and 1 is the default). So:
modprobe scsi_debug scsi_debug_num_devs=20 scsi_debug_add_host=0
will result in no scsi_debug hosts (thus no devices) but
the driver has 20 slots available for devices.
Then a host can be introduced (simulated hotplug) by
echo 1 > /sysfs/bus/scsi/drivers/scsi_debug/add_host
This causes a scsi_debug host to appear and devices get
found on it [14 in my system: 7 targets (0..6) each with
2 luns (0..1)]. Another host hotplug can be simulated by
echo 1 > /sysfs/bus/scsi/drivers/scsi_debug/add_host
which results in another 6 devices being attached (for a
total of 20 scsi_debug devices as dictated by the original
scsi_debug_num_devs).
That last (second) scsi_debug host can be removed by
echo -1 > /sysfs/bus/scsi/drivers/scsi_debug/add_host
and its 6 devices go. Another application of this "echo"
removes the first host and all remaining devices.
Seems to work fine.
<dougg@torque.net>
scsi_mid_low_api.txt
This patch against 2.5.46-bk3 is work in progress
(since the interface is in flux). It dusts of some
cobwebs, removes politically incorrect typedefs and
describes slave_attach() and slave_detach(). It
removes the revoke() description (per hch? changes).
Is a section describing mid level functions provided
for LLDDs (e.g. scsi_adjust_queue_depth() )
warranted?
<jejb@mulgrave.(none)>
warn (and don't attach) if no error handling
Add code to warn and not attach the host if it has no error handling.
Allow attachment if the `scsi_ignore_no_error_handling' boot flag
is set.
This should allow us finally to rip out all the old error code.
<sam@mars.ravnborg.org>
[ARM] makefile cleanup
Added prerequisite FORCE in several rules, now kbuild build a kernel even
the second time you try.
Corrected several errors to avoid errornous rebuild of targets in arch/arm
Lot's of trivial clean-up
<jejb@mulgrave.(none)>
[SCSI] downgrade lack of eh to warning and stack dump
<zaitcev@redhat.com>
include/asm-sparc/elf.h: Include uaccess.h

[IPSEC]: More fixes and corrections.
- Make connect() policy selection actually happen
- return len instead of 0 on successful pfkey sendmsg
- make prefixlen checks in a way more compatible with isakmpd
- key manager wait queues are totally wrong
<bcollins@debian.org>
[TG3]: TG3_HW_STATUS_SIZE should be 0x50 not 0x80.

the ACL support.
<davem@nuts.ninka.net>
net/ipv4/arp.c: Fix compiler warning.

[IPSEC]: Make netlink user interface header.
<dougg@torque.net>
scsi_debug 1.64 against 2.5.47
This is essentially the same patch that I sent earlier
today. The earlier patch will apply cleanly. However since
the 'sscanf("-1", "%d", &i)' bug is fixed in lk 2.5.47,
this attachment removes the work around.
lk 2.5.47 does not include the 'modprobe/rmmod' fixes from
Patrick Mansfield sent last week. They apply cleanly to
lk 2.5.47 and with them modprobe/rmmod cycles are stable
with scsi_debug.

[PATCH 0/2] clean up scsi documentation
here are my patches to clean up the scsi documentation. It is split in three
parts:
0) Do the work. A small script that does the following things:
-create Documentation/scsi/
-move all the scsi documentation from Documentation/ and drivers/scsi/ to this
location
-kill ChangeLog.serverraid. It's a duplication from ChangeLog.ips but is
missing some bits (got ok from maintainer to do this)
-rename README.drivername to drivername.txt which is more common in
Documentation/*
NOTE: start this script on the top level of the source tree (/usr/src/linux or
whereever you put it).
<eike@bilbo.math.uni-mannheim.de>
[PATCH] clean up scsi documentation
Ok, here comes part 2. Not mentioned in the first mail: it makes some minor
formatting changes in some comments.
Eike
<eike@bilbo.math.uni-mannheim.de>
[PATCH] clean up scsi documentation
And here are the final cleanups.
Eike
<hugh@veritas.com>
[PATCH] loop sendfile retval
Buffer I/O error on device loop: its use of sendfile is (trivially)
broken - retval is usually count done, only an error when negative.
This code (like the old one) does not correctly handle partial reads.
Nearby spinlocking clearly bogus, delete instead of remarking on it.
<viro@math.psu.edu>
[PATCH] CLONE_NEWNS fix
Spotted by Andries - cloning namespace assumes that new tree is
congruent to the old one (when switching root/cwd) but actually
inverts the order of children in each node.
<viro@math.psu.edu>
[PATCH] sys_swapoff() cleanup
Instead of user_path_walk() and comparing dentries, sys_swapoff()
opens its argument and compares ->i_mapping. Result: slightly
simpler code and swapoff(2) becomes tolerant to e.g.
swapon /dev/sda2
switch root from initrd to sda1
....
swapoff /dev/sda2 # where /dev is from sda1, not from initrd
current tree fails in the case above (different dentries -> no love).
<viro@math.psu.edu>
[PATCH] paride/pseudo.h cleanup
paride/pseudo.h fed through Lindent, use of timer replaced with
schedule_delayed_work() - that's what the old code tried to emulate.
<viro@math.psu.edu>
[PATCH] late-boot cleanups
RAID autoconfig rewritten to use syscalls and moved into do_mounts.c;
use of devfs_get_handle() in do_mounts.c also rewritten in syscalls.
<viro@math.psu.edu>
[PATCH] dm_ioctl() fix
Compile fixes, cleanup.
<viro@math.psu.edu>
[PATCH] ->pmtu compile fix
<viro@math.psu.edu>
[PATCH] bdevname() cleanups
Bunch of kdevname() uses replaced with bdevname().
__bdevname() switched from kdev_t to dev_t; callers updated.
<viro@math.psu.edu>
[PATCH] bd_dev cleanups
Eliminated several gratitious ->bd_dev uses.
<viro@math.psu.edu>
[PATCH] dasd fixe and cleanups
dasd.c forgot to set ->private_data, but was using it ;-/ Fixed.
Remaining dasd_devmap_from_kdev() callers switched to
dasd_devmap_from_bdev() (other than call from dasd_devmap_from_bdev(),
that is).
dasd_devmap_from_kdev() merged into dasd_devmap_from_bdev().
<viro@math.psu.edu>
[PATCH] misc cleanups
- compile fixes in amiflop.c
- removal of dead local variables in ll_rw_blk.c
- removed gratitious devfs_get_handle() in usb/input/hiddev.c
(no need to do lookup for "usb" and then create "hid" in
there - enough to create "usb/hid" at once).
<rusty@rustcorp.com.au>
[PATCH] KBUILD_MODNAME define for build system
By Kai Germaschewski.
This patch adds a -DKBUILD_MODNAME to the kernel compile, which
contains the base of the module name which is being built.
- Some sreorganization of the c_flags since they're needed for
generating modversions (.ver) and compiling
- Use the right KBUILD_MODNAME also when the user just wants a .i/.s/.lst
file for debugging and also when generating modversions
- It looks like with your current approach you can't have a ',' or '-' in
KBUILD_MODNAME - however, that means that KBUILD_MODNAME is not quite
right for passing module parameters for built-in modules on the command
line, it would be confusing to pass parameters for ide-cd as
ide_cd.foo=whatever. So that part could use a little more thought.
- If you think your module_names trick makes a noticable difference, feel
free to re-add it.
- It's possible that objects are linked into more than one module - I
suppose this shouldn't be a problem, since these objects hopefully
don't have a module_init() nor do they export symbols. Not sure if your
patch did handle this.
<rusty@rustcorp.com.au>
[PATCH] In-kernel Module Loader
This is an implementation of the in-kernel module loader extending
the try_inc_mod_count() primitive and making its use compulsory.
This has the benifit of simplicity, and similarity to the existing
scheme. To reduce the cost of the constant increments and
decrements, reference counters are lockless and per-cpu.
Eliminated (coming in following patches):
o Modversions
o Module parameters
o kallsyms
o EXPORT_SYMBOL_GPL and MODULE_LICENCE checks
o DEVICE_TABLE support.
New features:
o Typesafe symbol_get/symbol_put
o Single "insert this module" syscall interface allows trivial userspace.
o Raceless loading and unloading
You will need the trivial replacement module utilities from:
http://ozlabs.org/~rusty/module-init-tools-0.6.tar.gz

Re-introduce __MODULE_STRING, since some drivers depend on it.
(Yes, they should probably use __stringify() instead).
<davidel@xmailserver.org>
[PATCH] remove code duplication from fs/eventpoll.c
Clean up poll queue handling, avoid doing any wait-queue operations
when we only want to get the current state.
<mdharm-usb@one-eyed-alien.net>
[PATCH] usb storage: remmove unneeded abort checks
Since we now test for aborts at a higher level, the low-level end of the
drivers don't need to be constantly testing for aborts. This patch removes
that excess logic.
<mdharm-usb@one-eyed-alien.net>
[PATCH] usb storage: remove duplicate functions
Once upon a time, the SCSI command structure could only hold a maximum of
12 bytes. Thus, the ISD-200 driver needed an entirely separate function to
work with 16-byte commands.
Now that 16-bytes is stored, we can cut the duplicates.
<mdharm-usb@one-eyed-alien.net>
[PATCH] usb storage: fix aborted auto-sense
This patch fixes the case of an ABORT happening during the auto-sense
processing when using the ISD-200 driver.
<mdharm-usb@one-eyed-alien.net>
[PATCH] usb storage: fix spelling, comments.
This patch fixes some spelling errors and makes some comments a bit
more clear.
<mdharm-usb@one-eyed-alien.net>
[PATCH] usb storage: remove unneeded workaround for START_STOP
This patch removes the special-case code for START_STOP. It can be safely
removed now because the higher SCSI layers won't send this command unless
the device indicates that it needs it to allow media access.
<willy@debian.org>
[PATCH] Mux driver for PA-RISC
A driver for the Mux serial ports in some PA-RISC servers from Ryan Bradetich.
<ahaas@airmail.net>

ACPI: Interpreter update to 20021111 - Adds support for SMBus OpRegions
<david-b@pacbell.net>
[PATCH] <linux/device.h> KERN_WARN(ING)
This fixes <linux/device.h> so dev_warn() uses KERN_WARNING,
instead of a non-existent symbol. It also uses parens around
some arguments that need them ... those macros are now usable.

[PATCH] usbtest, add some unlink testcases
This adds some simple unlink test cases. I've only run these
against OHCI so far, and so far only in simple configurations
(only one active device), where it hasn't yet turned up problems.
<david-b@pacbell.net>
[PATCH] usbnet Kconfig helptext
Mostly just highlights the PDA support, now that we can say
this talks to all the Linux based PDAs; adds "more info" URL.
<david-b@pacbell.net>
[PATCH] USB: update usb hotplug documentation
<agrover@groveronline.com>
ACPI: Make unload/reload of modules work properly w.r.t. /proc
<agrover@groveronline.com>
ACPI: Do not compile code for EC unloading, because it cannot be unloaded atm
<david-b@pacbell.net>
[PATCH] ehci-hcd, use dummy td when queueing
What it does is give up on catching all the "race with HC" cases
when appending to a live QH, by switching to using a disabled
"dummy" TD at the end of all hardware queues. The HC won't cache
disabled TDs, so it just sees "always good" pointers: no races.
As a side benefit this also makes it safe to not irq on completion
of most TDs that are queued using the scatterlist calls, so it'll
be typical for one 64 KByte usb-storage request to mean just one
irq (or less!) even without tuning ehci irq latency (for the DATA
stage, that is).

[PATCH] Re: USB scanner fix for 2.5.47 was not good ?
Bad news is that the scanner endpoint change did not work, maybe I
mistested it or it never worked. My version worked, but was very ugly.
Here is a working one (against 2.5.47), this also looks nicer (I did not know the
EP_XXX() could be changed too):

[PATCH] rrunner PCI DMA mappings
This makes drivers/net/rrunner.[ch] use the PCI DMA mapping API. It
also fixes some potential SMP bugs where spin locks were taking outside
of interrupt context without disabling interrupts.
<david-b@pacbell.net>
[PATCH] usb problems (ohci-hcd + printer)
This fixes a number of issues in OHCI:
- Force out the PCI write disabling control/bulk queues.
This "shouldn't" matter, they're empty.
- The rule is that if an ED is IDLE, its OK to just
schedule it and start appending TDs. Hard to do that
when the typical error path left them still halted!
- Sometimes ed->hwTailP needs updating when TDs are
removed from the queue, not just ed->hwHeadP. Oops.
- Oh, and it's not the high bits we want to save when
we unlink ... it's the low bits (actually just toggle).
Except for forcing the writes to the controller, these patches should
only affect (improve :) fault and unlink handling.

[PATCH] Sparc and Sparc64 Module updates
My patch accidentally deleted module_map and module_unmap, which Sparc64
uses to get 32-bit memory (Sparc64 was the entire reason the arch has to
supply the module allocation functions, and then I didn't use it. Doh).
Plus a thinko in relocation calculation (dunno how that ever worked).

dynamic device info flag entries
This patch allows scsi device flags like those in the current scsi_scan.c
device_list to be added via the command line or via /proc/scsi/device_info.
It also allows a default flag to be set via the command line.
This should allow for the (eventual) removal of the current device_list.
Example boot command line arguments:
scsi_default_dev_flags=0x1 scsi_dev_flags="IBM:LN V1.2Rack:0x200"
The above means that a SCSI device with vendor "IBM ", model
(product) "LN V1.2Rack " will get a flag of 0x200 during scanning,
meaning it should be treated like a SCSI-3 device for scanning. All
other devices without an entry would get the default flag value of 1,
so they would not be scanned past LUN 0 (the same behaviour as
max_scsi_luns = 1).
I left the old device list and BLIST defines in scsi_scan.c.
I could not get lilo to allow two spaces, so I could not use this
with my device that has model "ST318203LC !#". I didn't try grub.

[PATCH] usb_new_device() sets up dev->dev earlier
This mostly moves the initialization of some sysfs-related
fields earlier, so HCD code can access them during those
(initial error prone) parts of enumeration without oopsing.
The particular access I wanted was using <linux/driver.h>
debug utilities like dev_dbg(), dev_warn() and so on ... so
I also changed the name the "generic" driver gives itself
to be "usb" so those messages make more sense.
Also added comments about how usb_new_device() moves the
device through the other chapter 9 usb device states.
<david-b@pacbell.net>
[PATCH] cleanup usb hcd unlink code
This fixes various minor problems:
- re-orders some tests so that "(no bus?)" diagnostic should
no longer be appearing (and making folk worry needlessly)
- removes one unreachable test for URB_TIMEOUT_KILLED
- removes the reachable test, since it's never an error on the
part of the device driver to unlink something the HCD is already
unlinking.
- gets rid of some comments and code that expected automagic resubmits
for interrupts (no more!),
- resolves a FIXME for a rather unlikely situation (HCD can't
perform the unlink, it reports an error)
It also starts to use dev_dbg() macros, which give more concise
(lately) and useful (they have both driver name and device id)
diagnostics than the previous usb-only dbg() macros. To do this,
DEBUG had to be #defined before <linux/driver.h> is included, but
it can't be #undeffed before <linux/kernel.h> is included.

[PATCH] ohci-hcd, driverfs files work again, less debug output
This fixes a problem from Chris' patch, letting the driverfs files
work again. The root cause was a duplicate "parent_dev" field,
now gone. This also adds minor cleanup in the hcd glue, renaming
the value being duplicated as the "controller" that the HCD is
driving. (A "parent" should rarely be used, but the "controller"
has reasonable uses all over the place ... like in dev_dbg calls!)
It's initted by the PCI bus glue, or by the SA-1111 bus glue.
Also makes some OHCI debug messages appear only when VERBOSE debug
is (manually) enabled. This was self-defense, otherwise running
the link/unlink "usbtest" cases could fill up the log filesystem
(with debug enabled).

[PATCH] HID patches for MGE UPS
I thought I'd send the results of some experimentation of mine getting
an MGE UPS (Evolution) to talk to 2.5 ... basically it behaved after
some patches, though the "hidups" driver didn't. They're all attached:
- "hiddev-1.patch" ... The default queue size was so small that this
low-speed device couldn't queue up about 110 control requests
(that many reports to check!) during init.
- "hiddev-2.patch" ... Makes hid debug output more useful by
(a) making it compile again;
(b) adding lots of "Power Device" and "Battery System" reports,
and putting all that data into the readonly data section;
(c) actually printing the usage strings, if they're known;
(d) printing a message when neither input nor hiddev claim
the device ... likely something's wrong, like someone
didn't configure in input subsystem or hiddev support.
- "hiddev-3.patch" ... Teaches hiddev to expose the physical ID
just like the input event framework does. Useful to help sort
out which UPS is which, so you won't power down the wrong set
of servers by accident.

fix potential panic due to scsi_init_io failure [axboe@kernel.dk]
This is the problem I have solved (incorrect segments), but it also
shows a nasty bug in SCSI.
If scsi_init_io() fails there, it calls scsi_end_request() which ends
the entire request. That calls __scsi_release_command() which clears
SCpnt->request (its now gone), but you then proceed to
scsi_mlqueue_insert() which ends up doing blk_insert_request() on
SCpnt->request. Boom.
Problem is there are two possible reason to return failure from init_io.
So we need to do the requeue inside init_io.

[PATCH] incorrect block layer segment accounting
There's a long standing bug in blk_recount_segments(). Clustering means
physical segment colascing, not hardware segment colascing. This
basically means that we are mapping more segments than here than the bio

adapters that have CLUSTERING enabled.
This patch makes sure that we are clustering physical segments
correctly, and correctly accounting hardware segments. Please apply.

[PATCH] run flush_cache_page while pte is valid
Patch from Hugh Dickins <hugh@veritas.com>
On some architectures (cachetlb.txt gives HyperSparc as an example)
it is essential to flush_cache_page while pte is still valid: the
rmap VM diverged from the base 2.4 VM before that fix was made,
so this error has crept back into 2.5.
Patch below applies to 2.5.47 or 2.5.47-mm1 - needs more work over
shared pagetables, but they've silently fallen out of 2.5.47-mm1:
oversight? I'll send Alan the equivalent for 2.4-ac shortly.
(I wonder, what happens if userspace now modifies the page
after the flush_cache_page, before the pte is invalidated?)

[PATCH] handle pages which alter their ->mapping
Patch from Hugh Dickins <hugh@veritas.com>
tmpfs failed fsx+swapout tests after many hours, a page found zeroed.
Not a truncate problem, but mirror image of earlier truncate problems:
swap goes through mpage_writepages, which must therefore allow for a
sudden swizzle back to file identity.
Second time this caught us, so I've audited the tree for other places
which might be surprised by such swizzling. The only others I found
were (perhaps) in the parisc and sparc64 flush_dcache_page called
from do_generic_mapping_read on a looped tmpfs file which is also
mmapped; but that's a very marginal case, I wanted to understand it
better before making any edit, and now realize that hch's sendfile
in loop eliminates it (now go through do_shmem_file_read instead:
similar but crucially this locks the page when raising its count,
which is enough to keep vmscan from interfering).

[PATCH] hugetlb cleanups
A rollup of Bill's 11-patch series which replaces hugetlb's custom
inode with a bare radix tree. Reviewed and acked by Rohit.
- revert doublefreeing patch
- Put set_new_inode() and the inode allocation loop into an
alloc_key(), and introduce a new opaque type "struct hugetlb_key".
- Wrap the release path in alloc_shared_hugetlb_pages() with a
release_key() function that handles the release.
- Wrap hugetlb_prefault() with prefault_key() in order to isolate the
dependency on inodes for prefaulting the hugetlb vma.
- Replaces the usage of inode->i_writecount as a flag marking keys
busy with a boolean flag field in struct htlbpagekey, and removes the
last dependency of alloc_shared_hugetlb_pages() on struct inode.
- Remove the last direct usage of struct inode within the hugetlb
functions.
- Removes many direct usages of struct inode within the key
manipulation API in exchange for passing references to the key
structure itself.
- Expand out prefault_key() into its hugetlb_prefault() component,
but substitute stubs to abstract out inode access.
- Move uid/gid/mode/size fields used in struct inode and the checks
on them into key management code and structures.
- Substitute direct usage of radix trees for inodes, and removes the
custom-allocated inodes.
- Wrap up the release path by adding proper refcounting of keys.
<akpm@digeo.com>
[PATCH] more hugetlb fixes
Patch from Rohit Seth, changelog from Bill Irwin:
(1) fixes failure to clear key->busy (yes, it's always under a lock)
(2) fixes key->count being unconditionally set to 1 in alloc_key()
(3) reduces search to key->size >> HPAGE_SHIFT from key->size
(4) actually uses vma->vm_private_data to release the key as intended
plus the cleanup:
(5) removes the int *new argument to alloc_key()

[PATCH] improved slab error diagnostics
slab does various consistency checks during `cat /proc/slabinfo'

The patch also removes an uninteresting printk from the boot process.
<akpm@digeo.com>
[PATCH] try to remove buffer_heads from to-be-reaped inodes
Stephen Tweedie reports a 2.4.7 problem in which kswapd is chewing lots
of CPU trying to reclaim inodes which are pinned by buffer_heads at
i_dirty_buffers.
This can only happen when there's memory pressure on ZONE_HIGHMEM - the
2.4 kernel runs shrink_icache_memory in that case as well. But there's
no reclaim pressure on ZONE_NORMAL so the VM is never running
try_to_free_buffers() against the ZONE_NORMAL buffers which are pinning
the inodes.
The 2.5 kernel also runs the slab shrinkers in response to ZONE_HIGHMEM
pressure. This may be wrong - still thinking about that.
This patch arranges for prune_icache to try to remove the inode's buffers
when the inode is to be reclaimed.
It also changes inode_has_buffers() and the other inode-buffer-list
functions to look at inode->i_data, not inode->i_mapping. The latter
was wrong.

[PATCH] better inode reclaim balancing
The inode reclaim is too aggressive at present - it is causing the
shootdown of lots of recently-used pagecache. Simple testcase: run a
huge `dd' while running a concurrent `watch -n1 cat /proc/meminfo'.
The program text for `cat' gets loaded from disk once per second.
This is in fact because the dentry_unused reclaim is too aggressive.
(The general approach to inode reclaim is that it _not_ happen at the
inode level. All the aging and lru activity happens at the dcache
level.)
The problem is partly due to a bug: shrink_dcache_memory() is returning
the *total* number of dentries to the VM, rather than the number of
unused dentries.
This patch fixes that, and goes a little further.
We do want to keep some unused dentries around. Reclaiming the last
few thousand dentries is pretty pointless, and will allow reclaim of
the last few thousand inodes and their attached pagecache.
So the algorithm I have used is to not allow the number of unused
dentries to fall below the number of used ones. This keeps a
reasonable number of dentries in cache while providing a level of
scaling to the system size and the current system activity.
(Magic number alert: why not pin nr_unused to seven times nr_used,
rather than one times??)
shrink_dcache_memory() has been changed to tell the VM that the number
of shrinkable dentries is:
zero if (nr_unused < nr_used)
otherwise (nr_unused - nr_used)
so when there is memory pressure the VM will prune the unused dentry
cache down to the size of the used dentry cache, but not below that.
The patch also arranges (awkwardly) for all modifications of
dentry_stat.nr_dentry to occur inside dcache_lock - it was racy.

[PATCH] eliminate pci_dev name
This removes the pci_dev "->name[]" field, and makes users use the
"struct device" name field instead.
It also trimps it down to 50 bytes and limited the length of the vendor
& device descriptions to 20 bytes each. Now we have three cases:
- unknown vendor & unknown device -> "PCI device %04x:%04x".
Clearly limited to 21 chars.
- known vendor, unknown device -> "PCI device %04x:%04x (%.20s)"
24 + 20 chars
- known vendor, known device -> "%.20s %.20s"
20 + 1 + 20 + 1, EXCEPT:
- multiple devices of the same type add " (#%d)"
so 42 + 4 + 4 = 50. This is the point where an IBMer tells me they
intend to sell a machine with > 9999 PCI devices of the same type ;-)
This limits the PCI IDs to a reasonable amount of space.
For release, I think we do want to go back up to 80 for prettier output

[PATCH] epoll - just when you think it's over ...
This does:
- naming cleanup: ep_* -> eventpoll_* for non-static functions ( 2 )
- No more limit of 2 poll wait queue for each file*
Before epoll used to have, inside its item struct, space for two wait
queues. This was driven by the fact that during a f_op->poll() each file
won't register more than one read and one write wait queue. Now, I'm not
sure if this is 100% true or not, but with the current implementation a
linked list of wait queues is kept to remove each limit.

[PATCH] additional cleanup for f_op->poll
This splits poll_table into one structure used by f_op->poll and one
structure used by the implemenation of sys_poll/sys_select: poll_table
contains just the callback function pointer. struct poll_wrapper
additionally contains err and table, i.e. the members used by the poll
implementation.
Changes:
- split poll_table into 2 structures
- reorder the declarations in <linux/poll.h> accordingly
- uninline poll_initwait().

[PATCH] yenta resource handling bugs
This adds error handling to the resource allocations in yenta.c: check
that request_resource returns success, reduce allocation size if
allocate_resource fails, free resources on module unload.

[PATCH] cleanup: switch to passing *(struct rpc_procinfo) in rpc_message.
The "procedure number" has been used for 2 purposes in the kernel
client RPC implementation:
1) As a number to pass to the server in the RPC header.
2) As an index into the "procedure array" of type 'struct
rpc_procinfo', from which the RPC layer can find the XDR
encode/decode functions, buffer size, and all the other static
data that it needs to construct the on-wire RPC message.
This works fine for NFSv2, v3 and for the NLM locking code for which
there is a one-to-one mapping between NFS file operations, and RPC
procedures.
For NFSv4 on the other hand, the mapping is many-to-one, since there
is only one RPC procedure number: NFSPROC4_COMPOUND.
For efficiency purposes, we want to have a one-to-one mapping between
NFS file operations and the corresponding XDR encode/decode routines,
but currently this is not possible because of (2). The result is the
mess that is 'struct nfs4_op' and encode/decode_compound.
In the process eliminating (2), we might as well change to passing a
pointer to the appropriate procedure array entry instead of an
index. This change can be made transparent
The appended patch therefore does the following:
- Substitute a pointer to the rpc_procinfo instead of the RPC
procedure number in the struct rpc_message.
- Make the RPC procedure number an entry in the struct
rpc_procinfo.
- Clean out the largely unused (except in some obscure lockd
debugging code) p_name field. The latter was just a stringified
version of the RPC procedure name, so for those lockd cases, we
can use the RPC procedure number instead.

fs.h is pulling so much crap in.. No need to include net.h in fs.h if
we move struct sock_alloc to net.h (which already includes fs.h through

Since we store two hardware pte tables contiguously, a common

[PATCH] Allocate struct module using special allocator
Sparc64 (and probably others) need all the kernel symbols within

This changes the interface back to its old style: the arch-specific code
manipulates the init and core sizes, and we call module_alloc() ourselves.

This is the logical counterpoint to the code which marks modules

doubly clear.

[PATCH] threading fix, tid-2.5.47-A3
This introduces the sys_set_thread_address() syscall. It sets the tid
address (which gets cleared at VM release time) and returns the PID so
that the newly initialized 'initial thread' does not have to do an
additional sys_gettid() call.
It is used to bootstrap a thread group where the original thread user
hasn't had a tid address assigned to it by any parent.

[PATCH] nanosecond stat timefields
stat64 has been changed to return jiffies granuality as nsec in previously
unused fields. This allows make to make better decisions on when
to recompile a file. Follows losely the Solaris API.
CURRENT_TIME has been redefined to return struct timespec. The users
who don't use it in a inode/attr context have been changed to use a new
get_seconds() function. CURRENT_TIME is implemented by an out-of-line
function.
There is a small performance penalty in this patch. The previous
filemap code had an optimization to flush atime only once a second.
This is currently gone, which will increase flushes a bit. I believe
the correct solution if it should be a problem is to have per super
block fields that give an arbitary atime flush granuality - so that you
can set it to be only flushed once a hour if you prefer that. I will
work on that later in separate patches if the need should arise.
struct inode and the attr struct has been changed to store struct
timespec instead of time_t for [cma]time. Not all file systems support
this granuality, but some like XFS,NFSv3,CIFS,JFS do. The others will
currently truncate the nsec part on flushing to disk. There was some
discussion on this rounding on l-k previously. I went for simple
truncation because there is not much evidence IMHO that the more
complicated roundings have any advantages. In practice application will
be rather unlikely to notice the rounding anyways - they can only see a
difference when an inode is flush from memory and reloaded in less than
a second, which is rather unlikely.

[PATCH] devfs_remove() helper
All callers of devfs_find_and_unregister() pass 0 in 6th argument. All
uses of that function either pass 0 in 3rd and 4th argument (in which
case the 5th is ignored) or pass the existing pathname in the 2nd (in
which case 3rd, 4th and 5th are ignored). In all cases the first
argument can be trivially made NULL.
devfs_find_and_unregister() is left as-is. All existing callers
converted to new helper - devfs_remove(pathname). Said beast does
equivalent of devfs_find_and_unregister(NULL, pathname, 0, 0, 0, 0);

[PATCH] more bogus MOD_INC_USE_COUNT removals
- example in Documentation/DocBook/procfs_example.c uses
MOD_..._USE_COUNT for no reason.
- alpha/kernel/srm_env.c uses MOD_...USE_COUNT for no reason _and_ does
lovely stuff like strlen() on user-supplied pointers,
copy_from_user() with unverified size, half-kilobyte on-stack arrays,
etc. Fixed.
- s390{,x}/kernel/debug.c: set ->owner instead of playing with
MOD_..._USE_COUNT in ->open()/->release()
- mwavedd.c: gratitious use of MOD_..._USE_COUNT
- uinput.c: ditto
- radio/miropcm20-rds.c: set ->owner, remove MOD_..._USE_COUNT from
->open()/->release(), fixed an obvious race in the former (it checked
that nobody else had device opened, then did kmalloc() with
GFP_KERNEL, then marked device as opened).
