Summary of changes from v2.5.38 to v2.5.39
============================================
<kai@tp1.ruhr-uni-bochum.de>
ISDN: per net device auto hangup function
Preparing for a hangup timer per ISDN netdevice instead of always
walking the list of all devices, separate out what we need to do
per device.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Switch isdn_net_hangup() to work on isdn_net_local *
Most other isdn_net functions operate on isdn_net_local *, so should
isdn_net_hangup() do.
<green@angband.namesys.com>
Reiserfs: Fix alloc= mount option parser.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: clean up i386 subarch build
These O_TARGETs keep coming back ;)
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Fix modversions generation glitch
Some people have their "cd" command print $PWD, so they would end
up with $PWD in their include/modversions.h, which is not quite what we
want.
<acme@conectiva.com.br>
[LLC] remove not needed functions, use llc_sap_find in llc_sock
With this I'm slowly (real job hampering progress ;) ) going down
the road that will allow me to remove llc_ui_sockets and llc_opt->sk_list,
using only the per llc_sap linked lists.
<acme@conectiva.com.br>
[LLC] kill llc_ui_bh_find_sk_by_addr
We can just use llc_lookup_established, one less user of llc_ui_sockets.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: per-interface hangup timer
After the preparation, switching to a per-interface timer is
now trivial.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Clean up tags/TAGS targets
They were partially broken by the SUBDIRS changes and could need
some cleanup anyway.

(fd_eject()).
<viro@math.psu.edu>
[PATCH] tapeblock blk_size removal
tapeblock never assignes anything to its elements of blk_size[][]; we could

It is the same bug fixed some months ago in tcp_v6_get_port,
i.e. we can't touch ipv6 private areas without checking if
the socket is AF_INET6.
<jgarzik@mandrakesoft.com>

<acme@conectiva.com.br>
[LLC] use sk->state_change when p_flag is cleared or core state changes
<acme@conectiva.com.br>
[LLC] use the core lists to get info for /proc/net/llc
With this llc_ui_sockets is almost not needed anymore, next
changesets will deal with the dataunit/xid/test primitives, that
are still using it.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: PPP cleanups
o PPP_IPX is defined in a header these days
o isdn_net_hangup takes an isdn_net_local *, simplifying
code a bit.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Kill isdn_net_autohup()
It's not used for the timeout controlled hangup anymore, only to
hangup depending on the dialmode, which we handle directly now.
<acme@conectiva.com.br>
[LLC] Make llc_save_primitive ready for dataunit/xid/test DGRAM packets
<kai@tp1.ruhr-uni-bochum.de>
ISDN: ISDN_GLOBAL_STOPPED cleanup
ISDN_GLOBAL_STOPPED is a way to globally stop the system
from dialing out / accepting incoming calls. Instead of
spreading checks all over the place, just catch dial
commands / incoming call indications in one place.
Also, kill isdn_net_phone typedef and clean up affected code.
<davem@nuts.ninka.net>
[BRIDGE]: Missing headers from ebtables merge.
<davem@nuts.ninka.net>
net/ipv4/netfilter/ip_conntrack_proto_tcp.c: Include linux/string.h
<acme@conectiva.com.br>
[LLC] move reason to the {station,sap,conn}_ev structs
Slowly killing the ugly struct forest.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Use <linux/list.h> for list of phone numbers
Simplifies the code which was previously using an open coded
singly linked list.
Also, deleting a phone number during dial-out could easily oops
the kernel before this patch.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Lock list of phone numbers appropriately
It was (only partially) protected by cli() before, which we want to
get rid of.
<akpm@digeo.com>
[PATCH] fix ext3 in data=writeback mode
When I converted ext3 to use to use direct-to-BIO writeback for
data=writeback mode I forgot that we need to hold a transaction open on
behalf of MAP_SHARED pages. The fileystem is BUGging in get_block()
because there is no transaction open.
So let's forget that idea for now and send data=writeback mode back to
ext3_writepage.
<akpm@digeo.com>
[PATCH] don't hold mapping->private_lock while marking a page dirty
__set_page_dirty_buffers() is calling __mark_inode_dirty under
mapping->private_lock.
We don't need to hold ->private_lock across that call. It's only there
to pin page->buffers.
This simplifies the VM locking heirarchy.
<akpm@digeo.com>
[PATCH] infrastructure for monitoring queue congestion state
The patch provides a means for the VM to be able to determine whether a
request queue is in a "congested" state. If it is congested, then a
write to (or read from) the queue may cause blockage in
get_request_wait().
So the VM can do:
if (!bdi_write_congested(page->mapping->backing_dev_info))
writepage(page);
This is not exact. The code assumes that if the request queue still
has 1/4 of its capacity (queue_nr_requests) available then a request
will be non-blocking. There is a small chance that another CPU could
zoom in and consume those requests. But on the rare occasions where
that may happen the result will mereley be some unexpected latency -
it's not worth doing anything elaborate to prevent this.
The patch decreases the size of `batch_requests'. batch_requests is
positively harmful - when a "heavy" writer and a "light" writer are
both writing to the same queue, batch_requests provides a means for the
heavy writer to massively stall the light writer. Instead of waiting
for one or two requests to come free, the light writer has to wait for
32 requests to complete.
Plus batch_requests generally makes things harder to tune, understand
and predict. I wanted to kill it altogether, but Jens says that it is
important for some hardware - it allows decent size requests to be
submitted.
The VM changes which go along with this code cause batch_requests to be
not so painful anyway - the only processes which sleep in
get_request_wait() are the ones which we elect, by design, to wait in
there - typically heavy writers.
The patch changes the meaning of `queue_nr_requests'. It used to mean
"total number of requests per queue". Half of these are for reads, and
half are for writes. This always confused the heck out of me, and the
code needs to divide queue_nr_requests by two all over the place.
So queue_nr_requests now means "the number of write requests per queue"
and "the number of read requests per queue". ie: I halved it.
Also, queue_nr_requests was converted to static scope. Nothing else
uses it.
The accuracy of bdi_read_congested() and bdi_write_congested() depends
upon the accuracy of mapping->backing_dev_info. With complex block
stacking arrangements it is possible that ->backing_dev_info is
pointing at the wrong queue. I don't know.
But the cost of getting this wrong is merely latency, and if it is a
problem we can fix it up in the block layer, by getting stacking
devices to communicate their congestion state upwards in some manner.
<akpm@digeo.com>
[PATCH] use the queue congestion API in ext2_preread_inode()
Use the new queue congestion detector in ext2_preread_inode(). Don't
try the speculative read if the read queue is congested.
Also, don't try it if the disk is write-congested. Presumably it is
more important to get the dirty memory cleaned out.
<akpm@digeo.com>
[PATCH] use the congestion APIs in pdflush
The key concept here is that pdflush does not block on request queues
any more. Instead, it circulates across the queues, keeping any
non-congested queues full of write data. When all queues are full,
pdflush takes a nap, to be woken when *any* queue exits write
congestion.
This code can keep sixty spindles saturated - we've never been able to
do that before.
- Add the `nonblocking' flag to struct writeback_control, and teach
the writeback paths to honour it.
- Add the `encountered_congestion' flag to struct writeback_control
and teach the writeback paths to set it.
So as soon as a mapping's backing_dev_info indicates that it is getting
congested, bale out of writeback. And don't even start writeback
against filesystems whose queues are congested.
- Convert pdflush's background_writeback() function to use
nonblocking writeback.
This way, a single pdflush thread will circulate around all the
dirty queues, keeping them filled.
- Convert the pdlfush `kupdate' function to do the same thing.
This solves the problem of pdflush thread pool exhaustion.
It solves the problem of pdflush startup latency.
It solves the (minor) problem wherein `kupdate' writeback only writes
back a single disk at a time (it was getting blocked on each queue in
turn).
It probably means that we only ever need a single pdflush thread.
<akpm@digeo.com>
[PATCH] low-latency page reclaim
Convert the VM to not wait on other people's dirty data.
- If we find a dirty page and its queue is not congested, do some writeback.
- If we find a dirty page and its queue _is_ congested then just
refile the page.
- If we find a PageWriteback page then just refile the page.
- There is additional throttling for write(2) callers. Within
generic_file_write(), record their backing queue in ->current.
Within page reclaim, if this tasks encounters a page which is dirty
or under writeback onthis queue, block on it. This gives some more
writer throttling and reduces the page refiling frequency.
It's somewhat CPU expensive - under really heavy load we only get a 50%
reclaim rate in pages coming off the tail of the LRU. This can be
fixed by splitting the inactive list into reclaimable and
non-reclaimable lists. But the CPU load isn't too bad, and latency is
much, much more important in these situations.
Example: with `mem=512m', running 4 instances of `dbench 100', 2.5.34
took 35 minutes to compile a kernel. With this patch, it took three
minutes, 45 seconds.
I haven't done swapcache or MAP_SHARED pages yet. If there's tons of
dirty swapcache or mmap data around we still stall heavily in page
reclaim. That's less important.
This patch also has a tweak for swapless machines: don't even bother
bringing anon pages onto the inactive list if there is no swap online.
<axboe@suse.de>
[PATCH] more bio updates
cleanup end_that_request_first() end_io handling, and fix bug where
partial completes didn't get accounted right wrt blk_recalc_rq_sectors()
<ink@jurassic.park.msu.ru>
[PATCH] Re: 2.5.36 IDE fixes
I'm terribly sorry - I've sent you the wrong diff, it was
some intermediate variant. Actually it added extra breakage to
ide_hwif_configure().
Desired behavior was:
if ctl == base == 0, the device is in "true legacy" mode (as per PCI
spec); use values from the base address registers otherwise.
<tim@physik3.uni-rostock.de>
[PATCH] trivial typo in drivers/ide/pci/sl82c105.c
<axboe@suse.de>
[PATCH] trm compile
Bad merge from 2.4.20-pre-ac, ide_build_dmatable() does not need data
direction argument in 2.5 (it's implicit in the request)
<axboe@suse.de>
[PATCH] pdc4030
make pdc4030 work
<axboe@suse.de>
[PATCH] bio_get_nr_vecs
Add bio_get_nr_vecs(). It returns an approximate number of pages that
can be added to a block device. It's just a ballpark number, but I think
this is quite fine for the type of thing it is needed for: mpage etc
need to know an approx size of a bio that they need to allocate. It
would be silly to continously allocate 64-page sized bio_vec entries, if
the target cannot do more than 8, for example.
<shaggy@kleikamp.austin.ibm.com>
JFS: Fix off-by-one error in dbNextAG
In certain situations, dbNextAG set db_agpref to db_numag, with is
one higher than the last valid value. This will eventually result in
a trap.
<mikpe@csd.uu.se>
[PATCH] fix UP_APIC linkage problem in 2.5.3[78]
The problem is that the local APIC code references stuff in
mpparse, but 2.5.37 changed arch/i386/kernel/Makefile to only
compile mpparse for SMP.
This patch works around this by enforcing CONFIG_X86_MPPARSE
for all LOCAL_APIC-enabled configs.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Convert missed L_TARGET references
When converting all L_TARGETs to lib.a, I missed these instances.
<frival@zk3.dec.com>
[PATCH] Compile fixes for alpha arch
Update alpha port to work with new nanosecond xtime, and the in_atomic()
requirements.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Fix build when CONFIG_ISDN_TTY_FAX is not set
T30_s * is part of a union, so the typedef needs to exist even when
CONFIG_ISDN_TTY_FAX is not set.
<torvalds@home.transmeta.com>
Terminate a failed IO properly
<mingo@elte.hu>
[PATCH] pidhash cleanups, tgid-2.5.38-F3
This does the following things:
- removes the ->thread_group list and uses a new PIDTYPE_TGID pid class
to handle thread groups. This cleans up lots of code in signal.c and
elsewhere.
- fixes sys_execve() if a non-leader thread calls it. (2.5.38 crashed in
this case.)
- renames list_for_each_noprefetch to __list_for_each.
- cleans up delayed-leader parent notification.
- introduces link_pid() to optimize PIDTYPE_TGID installation in the
thread-group case.
I've tested the patch with a number of threaded and non-threaded
workloads, and it works just fine. Compiles & boots on UP and SMP x86.
The session/pgrp bugs reported to lkml are probably still open, they are
the next on my todo - now that we have a clean pidhash architecture they
should be easier to fix.
<mingo@elte.hu>
[PATCH] de-xchg fork.c
This fixes all xchg()'s and a preemption bug.
<david-b@pacbell.net>
[PATCH] ohci-hcd, queue fault recovery + rm DEBUG
This USB patch updates the OHCI driver:
- converts to relying on td_list shadowing the hardware's
schedule; only collecting the donelist needs dma_to_td(),
and td list handling works much like EHCI or UHCI.
- leaves faulted endpoint queues (bulk/intr) disabled until
the relevant drivers had a chance to clean up.
- fixes minor bugs (unreported) in the affected code:
* byteswap problem when unlinking urbs ... symptom would
be data toggle confusion (since 2.4.2x) on big-endian cpus
* latent bug if folk unlinked queue in LIFO order, not FIFO
- removes unnecessary debug code; mostly de-BUG()ged
The interesting fix is the "leave queues halted" one. As
discussed on email a while back, this HCD fault handling
policy (also followed by EHCI) is sufficient to let device
drivers implement the two key fault handling policies that
seem to be necessary:
(a) Datagram style, where issues on one I/O won't affect
the next unless the device halted the endpoint. The
device driver can ignore most errors other than -EPIPE.
(b) Stream style, where for example it'd be wrong to ever
let block N+1 overwrite block N on the disk. Once
the first URB fails, the rest would just be unlinked
in the completion handler.
As a consequence of using the td_list, you can now see urb
queuing in action in the driverfs 'async' file. At least, if
you look at the right time, or use drivers (networking, etc)
that queue (bulk) reads for a long time.
<david-b@pacbell.net>
[PATCH] ehci-hcd: update
Here's an EHCI update, I'll send separate patches to sync 2.4 with
this version. Changes in this version include:
- An earlier locking update would give trouble on SPARC, where
irqsave "flags" aren't flags. This resolves that issue by
adding a module parameter to limit work done with irqs off.
(Some net drivers do the same thing.)
- Optionally (now #ifdef DEBUG) collects some statistics on IRQs
and URBs. There are more IAA interrupts than I want to see,
during extended usb-storage loading.
- Adds a commented-out workaround for a problem I've seen on one
VT8235. Seems likely an issue with this specific motherboard;
another tester hasn't reported such issues.
- Includes the jiffies time_after() patch from Tim Schmielau.
- Minor tweaks to the hcd portability (get rid of another #if).
- Minor doc/diagnostic/... updates
<david-b@pacbell.net>
[PATCH] USB shutdown oopser
is it guarenteed that callers have zero'd out the device
before this is invoked? Else the following is necessary to
prevent potential OOPS's derefencing interface->dev.driver in
the generic device layer.
<luc.vanoostenryck@easynet.be>
[PATCH] #include <linux/version.h> missing in drivers/usb/host/ohci-hcd.c
compile fails with the following message:
> In file included from ohci-hcd.c:136:
> ohci-dbg.c:318: parse error
> make[3]: *** [ohci-hcd.o] Error 1
due to a missing #include <linux/version.h>
Here is a trivial patch for this.
<stern@rowland.org>
[PATCH] usb-storage: fix return codes...
Like the header says, this patch fixes up the various Transfer- and
Transport-level return codes. There were a lot of places in the various
subdrivers that were not particularly careful about distinguishing the
two; it would help if the people currently maintaining those drivers could
take a look at my changes to make sure I haven't screwed anything up.
# Converted US_BULK_TRANSFER_xxx to USB_STOR_XFER_xxx, to make it more
# easily distinguishable from USB_STOR_TRANSPORT_xxx. (Also, in the
# future these codes may apply to control transfers as well as to bulk
# transfers.)
#
# Changed USB_STOR_XFER_FAILED to USB_STOR_XFER_ERROR, since it implies
# a transport error rather than a transport failure.
#
# Added a USB_STOR_XFER_STALLED code, to indicate a transfer that was
# terminated by an endpoint stall.
This patch is in preparation for one in which usb_stor_transfer_partial()
and usb_stor_transfer() are replaced by usb_stor_bulk_transfer_buf() and
usb_stor_bulk_transfer_srb() respectively, with slightly different
argument lists. Ultimately the subdrivers will be able to use these
routines in place of the slightly specialized versions they have now and
in place of the ones in raw_bulk.c.

[PATCH] USB: fix for ezusb firmware download
This fixes a stupid error in the timeout value when downloading firmware
to a device. The WhiteHEAT device now works properly with this patch.

[PATCH] USB: clean up the error logic for open() in the usb-serial driver
This cleans up the error path in the open() call to make a bit more
sense.

[PATCH] usb whiteheat driver update
Update to full working driver status. Latest firmware 4.06 too. Driver
now officially supported.
<info@usblcd.de>
[PATCH] USBLCD updates
-increased timeout value because some people reported problems
-(important!) Vender ID has changed from 0x1212 to 0x10D2 , my official
assigned one.
-added usblcd driver to configure.help
<mochel@osdl.org>
Driver model: improve support for system devices.
- Create struct sys_device to describe system-level devices (CPUs, PICs, etc.). This
structure includes a 'name' and 'id' field for drivers to fill in with a simple
canonical name (like 'pic' or 'floppy') and the id of the device relative to its
discovery in the system (it's enumerated value).
The core then constructs the bus_id for the device from these, giving them meaningful
names when exporting them to userspace:
# tree -d /sys/root/sys/
/sys/root/sys/
|-- pic0
`-- rtc0
- Replace
int register_sys_device(struct device * dev);
with
int sys_device_register(struct sys_device * sysdev);
- Fixup the users of the API.
- Add a system_bus_type for devices to associate themselves with. This provides a
bus/system/ directory in driverfs that looks like:
# tree -d /sys/bus/system/
/sys/bus/system/
|-- devices
| |-- pic0 -> ../../../root/sys/pic0
| `-- rtc0 -> ../../../root/sys/rtc0
`-- drivers
`-- pic
<mochel@osdl.org>
Driver model: handle devices registered with ->driver set.
In some cases, especially when dealing with system and platform devices, a
device's driver is known when the device is registered. We still want to add
the device to the driver's list and add it to the class.
This makes splits driver binding into probe() and attach(). If the device already
has a driver, we simply call attach(). Otherwise, we try to match it on the bus
and still call found_match().
This requires that all drivers that are referenced are registered beforehand.
<mochel@osdl.org>
USB: fixup handling of generic USB driver.
The generic driver is used by the virtual USB bridge device. This makes sure that
the driver is registered before we try to use it (and it gets the bus type right).
We also check for equality when matching devices to drivers, because we don't
want to match any device to it.
<mochel@osdl.org>
driver model: add support for CPUs.
- Create struct cpu to generically describe cpus (it simply contains
a struct sys_device in it).
- Define an array of size NR_CPUS in arch/i386/kernel/cpu/common.c
and register each on bootup. This gives us something like:
# tree -d /sys/root/sys/
/sys/root/sys/
|-- cpu0
|-- pic0
`-- rtc0
and:
# tree -d /sys/bus/system/devices/
/sys/bus/system/devices/
|-- cpu0 -> ../../../root/sys/cpu0
- Define arch-specific CPU driver that's also registered on boot.
That gives us:
# tree -d /sys/bus/system/drivers/
/sys/bus/system/drivers/
|-- cpu
- Create a CPU device class that's registered very early. That
gives us all the CPUs in the system in one place:
# tree -d /sys/class/cpu/
/sys/class/cpu/
|-- devices
| `-- 0 -> ../../../root/sys/cpu0
`-- drivers
Other archs are encouraged to do the same.

[PATCH] direct-io bandaid
The direct-IO code is currently generating 1 meg BIOs (and
subsequent BUGs) because it doesn't know about bio_add_page().
Could we please drop it to 16k until we get it sorted out?

driver model: add support for multi-board systems.
- device struct sys_root for describing the individual boards of a multi-board
system.
- allow for registration of alternate device roots.
- check if struct sys_device::root is set on registration, and add it as a child of
an alternative root, if it's set.
<mochel@osdl.org>
driver model: add better platform device support.
Platform devices are devices commonly found on the motherboard of systems. This
includes legacy devices (serial ports, floppy controllers, parallel ports, etc)
and host bridges to peripheral buses.
We already had a platform bus type, which gives a way to group platform devices
and drivers, and allow each to be bound to each other dynamically. Though before,
it didn't do anything. It still doesn't do much, but we now have:
- struct platform_device, which generically describes platform deviecs. This only
includes a name and id in addition to a struct device, but more may be added later.
- implelemnt platform_device_register() and platform_device_unregister() to handle
adding and removing these devices.
- Create legacy_bus - a default parent device for legacy devices.
- Change the floppy driver to define a platform_device (instead of a sys_device).
In driverfs, this gives us now:
a# tree -d /sys/bus/platform/
/sys/bus/platform/
|-- devices
| `-- floppy0 -> ../../../root/legacy/floppy0
`-- drivers
and
# tree -d /sys/root/legacy/
/sys/root/legacy/
`-- floppy0

[LLC] kill sap->{ind,conf}, finally!
With this one the sap->ind and ->conf callbacks are gone, now the core
is tightly integrated with the socket layer (PF_LLC) and the
datalink_protos are mostly working like when the old LLC stack was
in the kernel, i.e. without special receiving routines for IPX in
802.2 mode, now I have to work on the UI sending routines to kill more
stupid structs.

[PATCH] pgrp-fix-2.5.38-A2
This fixes the emacs bug reported by Andries. It should probably also
fix other, terminal handling related weirdnesses introduced by the new
PID handling code in 2.5.38.
The bug was in the session_of_pgrp() function, if no proper session is
found in the process group then we must take the session ID from the
process that has pgrp PID (which does not necesserily have to be part of
the pgrp). The fallback code is only triggered when no process in the
process group has a valid session - besides being faster, this also
matches the old implementation.
[ hey, who needs a POSIX conformance testsuite when we have emacs! ;) ]

[PATCH] fix null dereference in sys_mprotect
As it is at the moment, sys_mprotect will dereference a null pointer
if you use it on a region that is contained within the first vma. I
have a little program that demonstrates this (I'll post it if anyone
is interested). What happens then is that the process hangs in
do_page_fault at the down_read on the mm->mmap_sem, since sys_mprotect
has done a down_write on mm->mmap_sem.
The problem is that mprotect_fixup isn't updating prev properly. Thus
we can finish the main loop in sys_mprotect with prev == NULL. This
has been the case since Christoph's cleanups went in. Prior to that,
mprotect_fixup always set prev to something non-NULL. I suspect that
not updating prev could also cause vmas to get dropped completely if
the region being mprotected spans more than one vma.
The patch below fixes the problem by making mprotect_fixup set prev to
a reasonable value in all circumstances.

[PATCH] loop device broken in 2.5.38
The loop device driver was broken in 2.5.38 when it was converted over
to use gendisk. I discovered this while doing final regression testing
on the ext3 htree code.
The problem is that figure_loop_size() is setting the capacity of the
loop device in kilobytes (because that's what compute_loop_size()
returns), but set_capacity() expects the size in 512 byte sectors.
I've enclosed a patch which fixes the problem, as well as simplifying
the code by eliminating compute_loop_size(), since it is a static
function is only used once by figure_loop_size().
<mingo@elte.hu>
[PATCH] thread-flock-2.5.38-A3
Ulrich found another small detail wrt. POSIX requirements for threads -
this time it's the recursion features (read-held lock being write-locked
means an upgrade if the same 'process' is the owner, means a deadlock if a
different 'process').
this requirement even makes some sense - the group of threads who own a
lock really own all rights to the lock as well.
These changes fix this, all testcases pass now. (inter-process
testcases as well, which are not affected by this patch.)
(SIGURG and SIGIO semantics should also continue to work - there's some
more stuff we can optimize with the new pidhash in this area, but that's
for later.)
<mingo@elte.hu>
[PATCH] pidhash-2.5.38-A0
This removes the cmpxchg from the PID allocator and replaces it with a
spinlock. This spinlock is hit only a couple of times per bootup, so
it's not a performance issue.

This fixes a number of bugs in the thread-release code:
- notify parents only if the group leader is a zombie,

- do not reparent children to zombie tasks.
- introduce the TASK_DEAD state for tasks, to serialize the task-release
path. (to some it might be confusing that tasks are zombies first, then
dead :-)
- simplify tasklist_lock usage in release_task().
the effect of the above bugs ranged from unkillable hung zombies to kernel
crashes. None of those happens with the patch applied.

[PATCH] hugetlb fix
Patch from Rohit Seth
It fixes the problem which Andrea noted in his initial review of the
hugetlb code:
"In short doing "addr = vma->vm_end" and then checking if vm_end + len
is below vm_next->vm_start is broken, because there's no guarantee
that "addr" will be a largepage aligned address. the LPAGE_ALIGN in
found_addr should be dropped becaue moving the addr ahead without
checking that addr+len doesn't then fall into a vma, will generate
do_munmaps and in turn userspace mem corruption."

[PATCH] prepare_to_wait/finish_wait sleep/wakeup API
This is worth a whopping 2% on spwecweb on an 8-way. Which is faintly
surprising because __wake_up and other wait/wakeup functions are not
apparent in the specweb profiles which I've seen.
The main objective of this is to reduce the CPU cost of the wait/wakeup
operation. When a task is woken up, its waitqueue is removed from the
waitqueue_head by the waker (ie: immediately), rather than by the woken
process.
This means that a subsequent wakeup does not need to revisit the
just-woken task. It also means that the just-woken task does not need
to take the waitqueue_head's lock, which may well reside in another
CPU's cache.
I have no decent measurements on the effect of this change - possibly a
20-30% drop in __wake_up cost in Badari's 40-dds-to-40-disks test (it
was the most expensive function), but it's inconclusive. And no
quantitative testing of which I am aware has been performed by
networking people.
The API is very simple to use (Linus thought it up):
my_func(waitqueue_head_t *wqh)
{
DEFINE_WAIT(wait);
prepare_to_wait(wqh, &wait, TASK_UNINTERRUPTIBLE);
if (!some_test)
schedule();
finish_wait(wqh, &wait);
}
or:
DEFINE_WAIT(wait);
while (!some_test_1) {
prepare_to_wait(wqh, &wait, TASK_UNINTERRUPTIBLE);
if (!some_test_2)
schedule();
...
}
finish_wait(wqh, &wait);
You need to bear in mind that once prepare_to_wait has been performed,
your task could be removed from the waitqueue_head and placed into
TASK_RUNNING at any time. You don't know whether or not you're still
on the waitqueue_head.
Running prepare_to_wait() when you're already on the waitqueue_head is
fine - it will do the right thing.
Running finish_wait() when you're actually not on the waitqueue_head is
fine.
Running finish_wait() when you've _never_ been on the waitqueue_head is
fine, as ling as the DEFINE_WAIT() macro was used to initialise the
waitqueue.
You don't need to fiddle with current->state. prepare_to_wait() and
finish_wait() will do that. finish_wait() will always return in state
TASK_RUNNING.
There are plenty of usage examples in vm-wakeups.patch and
tcp-wakeups.patch.
<akpm@digeo.com>
[PATCH] use prepare_to_wait in VM/VFS
This uses the new wakeup machinery in some hot parts of the VFS and
block layers.
wait_on_buffer(), wait_on_page(), lock_page(), blk_congestion_wait().
Also in get_request_wait(), although the benefit for exclusive wakeups
will be lower.
<akpm@digeo.com>
[PATCH] slab reclaim balancing
A patch from Ed Tomlinson which improves the way in which the kernel
reclaims slab objects.
The theory is: a cached object's usefulness is measured in terms of the
number of disk seeks which it saves. Furthermore, we assume that one
dentry or inode saves as many seeks as one pagecache page.
So we reap slab objects at the same rate as we reclaim pages. For each
1% of reclaimed pagecache we reclaim 1% of slab. (Actually, we _scan_
1% of slab for each 1% of scanned pages).
Furthermore we assume that one swapout costs twice as many seeks as one
pagecache page, and twice as many seeks as one slab object. So we
double the pressure on slab when anonymous pages are being considered
for eviction.
The code works nicely, and smoothly. Possibly it does not shrink slab
hard enough, but that is now very easy to tune up and down. It is just:
ratio *= 3;
in shrink_caches().
Slab caches no longer hold onto completely empty pages. Instead, pages
are freed as soon as they have zero objects. This is possibly a
performance hit for slabs which have constructors, but it's doubtful.
Most allocations after a batch of frees are satisfied from inside
internally-fragmented pages and by the time slab gets back onto using
the wholly-empty pages they'll be cache-cold. slab would be better off
going and requesting a new, cache-warm page and reconstructing the
objects therein. (Once we have the per-cpu hot-page allocator in
place. It's happening).
As a consequence of the above, kmem_cache_shrink() is now unused. No
great loss there - the serialising effect of kmem_cache_shrink and its
semaphore in front of page reclaim was measurably bad.
Still todo:
- batch up the shrinking so we don't call into prune_dcache and
friends at high frequency asking for a tiny number of objects.
- Maybe expose the shrink ratio via a tunable.
- clean up slab.c
- highmem page reclaim in prune_icache: highmem pages can pin
inodes.

[PATCH] increase traffic on linux-kernel
[This has four scalps already. Thomas Molina has agreed
to track things as they are identified ]
Infrastructure to detect sleep-inside-spinlock bugs. Really only
useful if compiled with CONFIG_PREEMPT=y. It prints out a whiny
message and a stack backtrace if someone calls a function which might
sleep from within an atomic region.
This patch generates a storm of output at boot, due to
drivers/ide/ide-probe.c:init_irq() calling lots of things which it
shouldn't under ide_lock.
It'll find other bugs too.
<akpm@digeo.com>
[PATCH] speed up sys_sync()
Well it's a one-liner. sys_sync() only syncs one queue at a time, and
can be slow if you have a lot of disks. So poke pdflush, which knows
how to write all the queues in parallel.
<akpm@digeo.com>
[PATCH] tighter locking in pdflush
Had a weird oops from Bill Irwin - the pdflush_list was corrupt.
The only thing I can think of is that something sprayed out a wakeup
when it shouldn't. So tighten things up against that, and add some
printks to catch it if it happens again.

[PATCH] deadline ioscheduler cleanups
Some various small cleanups, optimizations, and fixes.
o Make fifo_batch=32 as default, from testing this appears a good
default value. We still get good throughput, and latency is good.
o Reintroduce the merge_cleanup logic. We need it for deadline for
rehashing requests when they have been merged.
o Cleanup last_merge logic. Move it to the new elv_merged_request(),
this is where it really belongs. Doing it inside the io scheduler core
can causes false positives, when the queue merge functions reject an
otherwise good merge
o Have deadline_move_requests() account from last entry on the dispatch
queue, if it is non-empty. It doesn't really matter what the last
extracted sector was, if we are not right behind it.
o Clean/optimize deadline_move_requests()
o Account size of a request just a little bit. Streaming transfer isn't
for free, it's just a lot cheaper than a seek.
o Make deadline_check_fifo() more readable.

[PATCH] io scheduler update
This fixes a problem with the deadline io scheduler, if the correct
insertion point is at the front of the list. This is something that we
never have gotten right in 2.4 either.
The problem is that the elevator merge function has to return a pointer
to a struct request, and for front insert we really have to return the
head of the list which cannot be expressed as a request of course.
The real issue is that the elevator_merge function actually performs two
functions - it scans for a merge, and if it can't find any, it selects
and insertion point. It's done this way for efficiency reasons, even if
the design isn't all that clean.
So we change the io scheduler merge functions to get passed a pointer to
a list_head pointer instead. This works for both inserts and merges.
In addition, deadline checks if it really should insert at the very
front.
Also don't pass in request to elv_try_last_merge(), the very name of the
function suggests that it's q->last_merge that we are interested in.

[PATCH] MODULE_LICENSE for i82092 pcmcia.
It appears that during the MODULE_LICENSE merge for pcmcia i82092 was
missed.
Here is a trivial patch to correct this.

[PATCH] more io scheduler updates
Small problem, we must of course also remember to take into account
where the last service point was (or will be).
deadline_get_last_sector() either returns the last offset serviced, or
the last one that will be (back of dispatch queue).
Otherwise the insert-at-head can be very unfair.

[PATCH] Minor ACPI changes for x86-64
Make CONFIG_ACPI_SLEEP dependent on software suspend (because suspend
is not working yet on x86-64)
Add support for the HPET tables.

[PATCH] Fix ELF name for x86-64
Align ELF binary name for x86-64 with ABI.
Required for the x86-64 merge in other mail.

[PATCH] Hammer aperture driver for 2.5.38
Add an AGP driver for the AGP aperture in the northbridge of the AMD Hammer.
The AGP driver works for both 32bit and 64bit kernels.
It also adds some hooks to the AGP driver to allow the x86-64 GART based
IOMMU code to share the aperture with AGP. The hooks are intentionally kept
minimalistic. In addition it needs some Config.in hackery, because AGP cannot
be modular in this case, because the IOMMU needs to control its startup and
it runs early when PCI is initialized.
The original AGP driver was done by Dave Jones, I added the IOMMU support.

[PATCH] disable early console in console_init
x86-64 has an early console implementation which runs before the normal
console is initialized. To avoid duplicated output it needs to be
disabled when the real console starts. This patch adds an function call
for that to the appropiate part of console_init.

[PATCH] virtual => physical page mapping cache
Implement a "mapping change" notification for virtual lookup caches, and
make the futex code use that to keep the futex page pinning consistent
across copy-on-write events in the VM space.
