Summary of changes from v2.5.48 to v2.5.49
============================================
<jgrimm@touki.austin.ibm.com>
[SCTP] sctp_params cleanup (jgrimm)
naming, purge typdef
add macro for walking parameters, stronger validity checks
<jgrimm@touki.austin.ibm.com>
[SCTP] More param handling, mostly handling hostname parm (jgrimm)
Per RFC, ABORT the peer if you don't want to support hostname parm.
Found/fixed potential div by zero.
Changed process_init to return error code, so its clients can do error handling.
<sridhar@dyn9-47-18-140.beaverton.ibm.com>
[SCTP] Support for Peer address parameters socket option.
<jgrimm@touki.austin.ibm.com>
[SCTP]: sctp_process_init can fail; cleanup and bail on errors. (jgrimm)
<rth@are.twiddle.net>
Fix carry ripple in 3 and 4 word addition and subtraction macros.
<jgrimm@touki.austin.ibm.com>
[SCTP] sctp_addr code cleanup.
Replace sockaddr_storage_t with 'union sctp_addr'.
Split up more ipv4/ipv6 code into af specific functions.
More later, but this gives me a base to do the rest.
<jgrimm@touki.austin.ibm.com>
[SCTP] Handle "no route" case for output handler (jgrimm)
<sridhar@dyn9-47-18-140.beaverton.ibm.com>
[SCTP] udp-style connect support(non-blocking).
<sridhar@dyn9-47-18-140.beaverton.ibm.com>
[SCTP] Fix for sideeffect violation in sctp_sf_heartbeat().
<jgrimm@touki.austin.ibm.com>
[SCTP] Addr family cleanup part 2. (jgrimm)
Splitting out yet more code. New af and pf specific functions.
<rth@are.twiddle.net>
Fix a whole pile of signed/unsigned comparison warnings.
From Thorsten Kranzkowski <dl8bcu@dl8bcu.de>.
<rth@are.twiddle.net>
Remove duplicate sys_rx164.o in GENERIC kernel.
From Adrian Bunk <bunk@fs.tum.de> via the Trivial Patch Manager.
<rth@are.twiddle.net>
Avoid multi-line string literal for asm block.
<rth@are.twiddle.net>
Add Alpha entry in MAINTAINERS.
<jgrimm@touki.austin.ibm.com>
[SCTP]: enable v6 autobinding.
This is just more address cleanup really, but the sideeffect is that
this enables the autobinding on PF_INET6 sockets.
<sridhar@dyn9-47-18-140.beaverton.ibm.com>
[SCTP] Blocking connect() support.
<dwmw2@infradead.org>
JFFS2 update.
Various bugfixes
-- deadlock in prepare_write() on extension of file fixed.
-- corruption when reading a page where a multi-page hole ends fixed.
-- oops on unlink of bad inodes fixed.
-- allow bi-endian operation; mounting of non-host-endian file system is now possible.
Optimisations
-- switch to rbtrees for the inode fragment list. O(log n) insertion and lookup now.
-- avoid checking all data crcs and building fragment trees at scan time. Do it later in GC.
-- use 'point' method if available to use a pointer directly into the flash chip during
scan, rather than always using memcpy into RAM first.
-- start to track node 'pristine' status, for later use in GC optimisation -- we'll be
able to copy those nodes intact without having to read them, decompress and
recompress their payload, etc. Or indeed having to read_inode() their inode.
-- fix ordering of work done from kupdated. We now erase a block, mark it free and stick
it on the appropriate list, and go on to the next one. Before, we erased _all_ the
pending blocks before marking any of them free, while everyone waited for us.
<sridhar@dyn9-47-18-140.beaverton.ibm.com>
[SCTP] MSG_EOR support for recvmsg().
<jgrimm@touki.austin.ibm.com>
[SCTP] PF_INET6 sockets should accept v4 addresses into association.
Yet more address split out, but with the sideeffect that PF_INET6
sockets can accept v4 addresses. Another sideeffect is that this
fixes an issue with the destination lookup code to deal with wildcards,
as the previous code was not considering the wildcard a match and
consequently doing a second lookup.
<agrover@groveronline.com>

<acme@conectiva.com.br>
o smbfs: fixup header cleanups: forward declare struct sock, add include/uio.h
<maneesh@in.ibm.com>
[PATCH] dcache usage cleanups
This cleans up the dcache code to always use the proper dcache functions
(d_unhashed and __d_drop) instead of accessing the dentry lists
directly.
In other words: use "d_unhashed(dentry)" instead of doing a manual
"list_empty(&dentry->d_hash)" test. And use "__d_drop(dentry)" instead
of doing "list_del_init(&dentry->d_hash)" by hand.
This will help the dcache-rcu patches.
<wli@holomorphy.com>

This patch makes the futex code check utime only when waiting.
This makes it possible to do futex wakes without clearing the register
containing the utime parameter.
The code also becomes cleaner.

driver model: typo in intf.c.
<joe@wavicle.org>
[PATCH] vicam.c
Included in this patch:
- (From John Tyner) Move allocation of memory out of send_control_msg. With
the allocation moved to open, control messages are less expensive since
they don't allocate and free memory every time.
- (From John Tyner) Change the behaviour of send_control_msg to return 0 on
success instead of the number of bytes transferred.
- Clean up of a couple down_interruptible() calls that weren't checking for
failure
- Rewrite of proc fs entries to use one file per value instead of parsing
in the kernel
<greg@kroah.com>
USB: vicam.c driver fixes

removed unneeded #ifdefs
removed bool nonsense.

problems with debug prints and comments.
<mdharm-usb@one-eyed-alien.net>
[PATCH] usb-storage: fix missed changes in freecom.c and isd200.c
This patch changes freecom.c and isd200.c to use the new data-moving logic
instead of the old data-moving logic. This allows for code consolidation
and better error-handling.
<mdharm-usb@one-eyed-alien.net>
[PATCH] usb-storage: code consolidation
This patch puts all the code to interpret the result code from an URB into
a single place, instead of copying it everywhere throughout transport.c
<rth@are.twiddle.net>

[PATCH] fix compile error in usb-serial.c
drivers/usb/serial/usb-serial.c in 2.5.48 fails to compile with the
following error:
drivers/usb/serial/usb-serial.c:842: dereferencing pointer to incompletetype
Is the following patch correct?
<rusty@rustcorp.com.au>
[PATCH] kallsyms for new modules
Since I believe kallsyms is important, this reimplements it sanely,
using the current module infrastructure, and not using an external
kallsyms script.
FYI, the previous interface was:
int kallsyms_symbol_to_address(
const char *name, /* Name to lookup */
unsigned long *token, /* Which module to start with */
const char **mod_name, /* Set to module name or "kernel" */
unsigned long *mod_start, /* Set to start address of module */
unsigned long *mod_end, /* Set to end address of module */
const char **sec_name, /* Set to section name */
unsigned long *sec_start, /* Set to start address of section */
unsigned long *sec_end, /* Set to end address of section */
const char **sym_name, /* Set to full symbol name */
unsigned long *sym_start, /* Set to start address of symbol */
unsigned long *sym_end /* Set to end address of symbol */
);
The new one is:
/* Lookup an address. modname is set to NULL if it's in the kernel. */
const char *kallsyms_lookup(unsigned long addr,
unsigned long *symbolsize,
unsigned long *offset,
char **modname);
<mochel@osdl.org>
kobject - expose backend helpers to registration interface.
The interface should now be more sane and protect against races better.
kobject_register() was split into two helpers: kobject_init() and kobject_add().
It calls both consecutively, though both are also exposed for use by users
that want to use the objects w/o adding them to the object hierarchy.
kobject_unregister() was made simply a wrapper for kobject_del() and
kobject_put(), which are both also exposed. The guts of kobject_put() was
moved into kobject_cleanup(), which it calls when the reference count hits
0. (This was done for clarity).
The infrastructure now takes a lot in kobject_get() and kobject_put() when
checking and modifying the objects' reference counts. This was an obvious
one that hsould have been fixed long ago.
kobject_add() increments the refcount of the object, which is decremented
when kobject_del() is called. This guarantees that the object's memory
cannot be freed if it has been added to the hierarchy, and kobject_del()
has not been called on it.
kobject_init() is now the function that increments the refcount on the
object's subsystem, which is decremented only after its release() method
has been called for the object in kobject_cleanup().
The documentation has been updated to reflect these changes.
<torvalds@home.transmeta.com>
Parts of "module.c" was needed even when no module support
was enabled, so split it up into "extable.c"
<rml@tech9.net>
[PATCH] ALSA compiler warnings fixes
Fix numerous ALSA core compiler warnings of the type "unused variable foo"
<trond.myklebust@fys.uio.no>
[PATCH] Support for micro/nanosecond [acm]time in the NFS client
Given Andi Kleen's patch that introduces of VFS-level support for
nanosecond time resolutions, we should finally be able to export the
existing NFS client level support to userland.
In order to do so, the following patch will convert all NFS private 'raw
u64' values into the kernel-supported struct timespec directly in the
xdr_encode/xdr_decode routines.
It adds support for the nanosecond field in NFS 'setattr' calls, and in
nfs_refresh_inode().
Finally, there are a few cleanups in the nfs_refresh_inode code that
convert multiple use of the NFS_*(inode) macros into a single
dereference of NFS_I(inode).

[PATCH] inode_mknod parameters
These security_ops are declared like
int (*inode_mknod) (struct inode *dir, struct dentry *dentry,
int mode, dev_t dev);
with a mode and a dev_t argument.
But the users mistakenly had major, minor instead of mode, dev.

[ARM] 2.5.48 Build fixes (round 1)
This cset applies the ARM fixups for various 2.5.48 changes, including
fixing ADFS. This cset does NOT contain ARM fixes for Rusty's 2.5.48
module changes.
<rmk@flint.arm.linux.org.uk>
[ARM] 2.5.48 module fixups (and disable module loading for ARM)
This cset implements half the changes required for Rusty's in-kernel
module loader. It implements the basic principles required to link
a module with other modules and the kernel, as well as providing the
required functions to allow the kernel to build with CONFIG_MODULES=y.
However, as an unfortunate side effect, this cset DISABLES the
ability to load modules on ARM; it's currently broken since we need
to allocate a jump table for out of range branches (which is required
for most calls from modules to the kernel binary to work.)
Since we don't know the size of the jump table until we come to link
the module, a subsequent vmalloc could return memory no where near
the module itself, giving the same problem.
<rmk@flint.arm.linux.org.uk>
[ARM] Undefine symbol "arm", update mach-types.
<bfennema@falcon.csc.calpoly.edu>
[PATCH] fix nanosecond stat timefields in UDF
<Andries.Brouwer@cwi.nl>
[PATCH] compilation fix (tpyo)
<torvalds@home.transmeta.com>
Broken applications do not realize that a zero return
from "write()" is an error condition, and hang retrying.
Return EINVAL in sysfs instead.
<mochel@osdl.org>
sysfs: do permission checking on open.
sysfs has always had a bug that would allow a read-only file to be opened
for writing. It has also returned 0 on write when there was no store method
defined for the file.
This addresses both via sysfs_open_file(). It checks the flags the file was
opened with and compares them with the mode of the inode. If the mode does
not support the flags passed, -EPERM is returned.
If the sysfs_ops for the object does not have the correct method for the
flags, -EACCESS is returned.
Since all checks happen on open(), the corresponding checks in the read()
and write() methods have been removed.
<rmk@flint.arm.linux.org.uk>
[ARM] 2.5.48 Build fixes (round 2)
This cset fixes various PCI and FPA11 FPE related build warnings and
errors resulting from changes from 2.5.47 to 2.5.48.
<rmk@flint.arm.linux.org.uk>
[ARM] Update ARM bitops to operate on unsigned long quantities.
This cset removes some complexity that arose due to the endian issues
caused by using byte accesses in the bitops. Since bitops are now
guaranteed to operate on unsigned long quantities, we can now use
word operations. This means that bitops bit 0 naturally falls into
word 0 bit 0.
<torvalds@penguin.transmeta.com>
Don't trust "rq->cmd_len", most of the internal IDE-CD command
sending routines don't set it up.
<ink@jurassic.park.msu.ru>
[PATCH] alpha: initrd vs. "mem=" fix
As the aboot always puts initrd image near the top of physical memory,
initrd is not accessible if we limit memory size with "mem=" argument.
Fixed by moving the image to the "low" memory if needed.
Also, some of these routines will be used by marvel (in non-NUMA config)
and up1500.

[PATCH] ADM8513 support added;
<chris@wirex.com>
[PATCH] sys_capget should use current if the pid argument is 0
<hch@lst.de>
[PATCH] make scsi_ioctl.h useable without including scsi.h
*grr* - silly typedefs..
<hch@lst.de>
[PATCH] rationalize allocation and freeing of struct scsi_device
Currently allocation and freeing of struct scsi_device is a mess.
We have two nice functions in scsi_scan.c (scsi_allocate_sdev/
scsi_free_sdev) that are the right interfaces to deal with it, so I moved
them to scsi and made them non-static. I've changed all functions
allocation freeing them to use it.
<hch@lst.de>
[PATCH] remove dead struct/typedef from hosts.h
<hch@lst.de>
[PATCH] remove unused includes and misleading comments from scsi_lib.c
Some of that stuff might have been right for 2.4, but..
(and btw, scsi_lib is pretty misleading, what about reusing scsi_queue.c?)
<jejb@mulgrave.(none)>
fix queue run on returning I/O [axboe@suse.de]
On returning I/O, need to unplug the queue before we call the queue_fn.
This fixes a problem in 2.5.48 where the aic7xxx driver hangs under e2fsck.
<dougg@torque.net>
scsi_debug 1.65 for lk 2.5.48
The scsi_debug version in lk 2.5.48 is the second last one
I sent to this list. So this patch includes the changes from
the last one I sent:
- fix "in use" counting [hch]
- clean up bios_param() code
It also merges a sysfs re-organisation from Mike Anderson.

It looks like the merge of Doug and Christoph's code dropped two calls
(unless the exit devfs_unregister was supposed to be removed).
Here's a patch for the addition of scsi_init_procfs, devfs_mk_dir and
bus_unregister calls, and a small reordering so calls in exit_scsi
match the reverse of those in init_scsi.
<mochel@osdl.org>
driver model: exploit kobject contstructs.
This makes the driver model core (for devices) exploit the kobject
infrastructure more and make the resulting code quite a bit simpler.
For one, device_register() mimmicks kobject_register() in that it now only
calls device_initialize() and device_add() back to back. Similarly,
device_unregister() calls device_del() and put_device() consecutively.
device_del() no longer removes and frees the device, it only removes them.
It also removes the devices from the global and sibling lists. This was
previously done by device_put(), but moved here to be symmetrical with
device_add().
The device's parent is now only incremented in device_add() and decremented
in device_del(), fixing a bug in which the parent's refcount was incremented
twice.
Because of these simplifications, the core can easily be converted to use
the kobject reference counting infrastructure. get_device() now simply
forwards the call to kobject_get() and ditto for put_device().
device_release() is implemented to handle the freeing of devices once their
reference count reaches 0.
Since we're using the kobject refcounting model, we no longer need the
checking or setting of the device state field, so it has been removed.
The only users of it were the power routines. In those, it is implicit that
we have a valid device, since we've already taken device_sem, and we're
walking the list (all modifications are protected by device_sem).
struct device::lock, and the helpers to lock/unlock have been removed. No
one has ever used them, and no one is likely to use them.

[PATCH] remove duplicated assignment from sys_capget.
This removes the code from cap_sysget that fills out the capability set
being returned to userspace. The module handles this in a policy
specific way. This updates the dummy.c module to fill in return data
according to superuser policy, and also disables setting capabilities in
superuser policy.

<Andries.Brouwer@cwi.nl>
[PATCH] *_mknod prototype
The dev_t argument of sys_mknod is passed to vfs_mknod, and is then cast
to int when foo_mknod is called, and is subsequently very often cast
back to dev_t. (For example, minix_mknod() calls minix_set_inode() that
takes a dev_t.)
This is a cleanup that avoids this back-and-forth casting by giving
foo_mknod a prototype with dev_t. In most cases now the dev_t is
transmitted untouched until init_special_inode.
It also makes the two routines hugetlbfs_get_inode() and
shmem_get_inode() static.

[PATCH] PCI: transparent bridge detection fix
The detection of subtractive decoding bridges is broken: `class' variable

[PATCH] Merge lcall7 and lcall27 code paths in ia32
lcall7 and lcall27 code paths are almost identical, except one
constant. This code merges these two paths together, by moving
constant to the beginning of function.
It is possible to eliminate even more of lcall7 and lcall27
code paths, but at cost of splitting SAVE_ALL into two halves,
and I do not want to do that. But if you think that it is worth
of effort, I can save 16 more bytes, but at cost of speed.
Side effects of merge is that now stack is addressed relative
to %ebx instead of relative to %esp, so generated code is
shorter and faster.

This cset allows ARM modules to work again. The solution was

We shrink the available user space size by 16MB, thereby opening up

direct mapped RAM. We place modules into this space, and, since the
kernel image is always at the bottom of kernel direct mapped RAM, we
can be assured that any 24-bit PC relocations (which have a range
of +/- 32MB) will always be able to reach the kernel.

sysfs: various updates.
- Don't do extra dget() when creating symlink.
This is a long-standing bug with a simple and obvious fix. We were doing
an extra dget() on the dentry after d_instantiate(). It only gets decremented
once on removal, so the dentry was never really going away, and the directory
wasn't, either.
- Use simple_unlink() instead of sysfs_unlink().
- Use simple_rmdir() instead of our own, unrolled, version.
- Remove MODULE_LICENSE(), since it's always in the kernel.
<mochel@osdl.org>
driver model: update and clean bus and driver support.
This a multi-pronged attack aimed at exploiting the kobject infrastructure mor.
- Remove bus_driver_list, in favor of list in bus_subys.
- Remove bus_for_each_* and driver_for_each_dev(). They're not being used by
anyone, have questionable locking semantics, and really don't provide that
much use, as the function returns once the callback fails, with no indication
of where it failed. Forget them, at least for now.
- Make sure that we return success from bus_match() if device matches, but
doesn't have a probe method.
- Remove extraneous get_{device,driver}s from bus routines that are serialized
by the bus's rwsem. bus_{add,remove}_{device,driver} all take the rwsem, so there
is no way we can get a non-existant object when in those functions.
- Use the rwsem in the struct subsystem the bus has embedded in it, and kill the
separate one in struct bus_type.
- Move bulk of driver_register() into bus_add_driver(), which holds the bus's
rwsem during the entirety. this will prevent the driver from being unloaded while
it's being registered, and two drivers with the same name getting registered
at the same time.
- Ditto for driver_unregister() and bus_remove_driver().
- Add driver_release() method for the driver bus driver subsystems. (Explained later)
- Use only the refcounts in the buses' kobjects, and kill the one in struct bus_type.
- Kill struct bus_type::present and struct device_driver::present. These didn't
work out the way we intended them to. The idea was to not let a user obtain a
rerference count to the object if it was in the process of being unregistered.
All the code paths should be fixed now such that their registration is protected with
a semaphore, so no partially initialized objects can be removed, and enough
infrastructure is moved to the kobject model so that once the object is publically
visible, it should be usable by other sources.
- Add a bus_sem to serialize bus registration and unregistration.
- Add struct device_driver::unload_sem to prevent unloading of drivers
with a positive reference count.
The driver model has always had a bug that would allow a driver with a
positive reference count to be unloaded. It would decrement the reference
count and return, letting the module be unloaded, without accounting for
the other users of the object. This has been discussed many times, though
never resolved cleanly. This should fix the problem in the simplest manner.
struct device_driver gets unload_sem, which is initialized to _locked_. When
the reference count for the driver reaches 0, the semaphore is unlocked.
driver_unregister() blocks on acquiring this lock before it exits. In the
normal case that driver_unregister() drops the last reference to the driver,
the lock will be acquired immediately, and the module will unload.
In the case that someone else is using the driver object, driver_unregister()
will not be able to acquire the lock, since the refcount has not reached 0,
and the lock has not been released.
This means that rmmod(8) will block while drivers' sysfs files are open.
There are no sysfs files for drivers yet, but note this when they do have
some.
<mochel@osdl.org>
driver model: make classes and interfaces use kobject infrastructure.
Like the other objects, this allows a decent bit of cleanup. Details include:
- use rwsem in subsytem, instead of one in struct device_class.
- use refcount in struct kobject, instead of one in struct device_class.
- kill class's present flag.
- kill class_list, since we can just use class_subsys's.
- make interfaces instances of their class's subsystem. This allows us to
kill struct device_class::intf_list, and struct device_interface::node.
<mochel@osdl.org>
USB: minor driver model-related updates.
- don't define and use a release callback for the generic driver.
- Call bus_unregister() in usb_exit() to remove the usb driver, instead of put_bus().
<mochel@osdl.org>
partitions: use the name in disk->kobj.name, instead of disk->disk_name.
Some names (for some reason) have a '/' in them, making them no good for directory
names. disk->kobj.name has already been transformed to turn those into '!', so this
makes sure we use those when setting the name for the partitions' names.

[PATCH] A new Athlon 'bug'.
Very recent Athlons (Model 8 stepping 1 and above) (XPs/MPs and mobiles)
have an interesting problem. Certain bits in the CLK_CTL register need
to be programmed differently to those in earlier models. The problem arises
when people plug these new CPUs into boards running BIOSes that are unaware
of this fact.
The fix is to reprogram CLK_CTL to 200xxxxx instead of 0x600xxxxx as it was
in previous models. The AMD folks have found that this improves stability.
The patch below does this reprogramming if an affected model/bios is
detected.
I'm interested if someone with an affected model could run some
benchmarks before and after to also see if this affects performance.

[PATCH] Split buffer overflow checking out of struct nfs4_compound
Here is the a pre-patch in the attempt to get rid of 'struct
nfs4_compound', and the associated horrible union in 'struct
nfs4_op'.
It splits out the fields that are meant to do buffer overflow checking
and iovec adjusting on the XDR received/sent data. It moves support
for that nto the dedicated structure 'xdr_stream', and the associated
functions 'xdr_reserve_space()', 'xdr_inline_decode()'.
The patch also expands out the all macros ENCODE_HEAD, ENCODE_TAIL,
ADJUST_ARGS and DECODE_HEAD, as well as most of the DECODE_TAILs.

[PATCH] disable old stat on ppc64
We don't implement the ancient stat syscalls on ppc64 since early libcs
wont run on ppc64 (they hardcode the incorrect cacheline size).

[PATCH] kNFSd - 1 of 2 - Change NFSv4 xdr decoding to cope with separate pages.
Now that nfsd uses a list of pages for requests instead of
one large buffer, NFSv4 need to know about this.
The most interesting part of this is that it is possible
that section of a request, like a path name, could span
two pages, so we need to be able to kmalloc as little bit
of space to copy them into, and make sure they get
freed later.
<neilb@cse.unsw.edu.au>
[PATCH] kNFSd - 2 of 2 - Change NFSv4 reply encoding to cope with multiple pages.
This allows NFSv4 responses to cover move than one page. There are
still limits though. There can be at most one 'data' response which
includes READ, READLINK, READDIR. For these responses, the interesting
data goes in a separate page or, for READ, list of pages.
All responses before the 'data' response must fit in one page, and all
responses after it must also fit in one (separate) page.

[PATCH] misc
- I hit a BUG in end_swap_bio_read() under heavy load. The page
wasn't locked. No idea how this can happen :(
Add a BUG at submission time to catch a caller reading into an
unlocked swapcache page.
- Remove a debug check from destroy_inode() - it was in the wrong leg
of the `if' statement anyway.

[PATCH] shmdt bugfix
Patch from Hugh Dickins <hugh@veritas.com>
Fixes the Oracle startup problem reported by Alessandro Suardi.
Reverts a "simplification" to shmdt() which was wrong if subsequent
mprotects broke up the original VMA, or if parts of it were munmapped.

[PATCH] radix-tree reinitialisation fix
This patch fixes a problem which was discovered by Vladimir Saveliev
<vs@namesys.com>
Radix trees have a `height' field, which defines how far the pages are
from the root of the tree. It starts out at zero and increases as the
trees depth is grown.
But it is never decreased. It cannot be decreased without a full tree
traversal.
Because radix_tree_delete() does not decrease `height', we end up
returning inodes to their filesystem's inode slab cache with a non-zero
height.
And when that inode is reused from slab for a new file, it still has a
non-zero height. So we're breaking the slab rules by not putting
objects back in a fully reinitialised state.
So the new file starts out life with whatever height the previous owner
of the inode had. Which is space- and speed-inefficient.
The most efficient place to fix this would be in destroy_inode(). But
that only fixes the problem for inodes - there are other users of radix
trees.
So fix it in radix_tree_delete(): if the tree was emptied, reset
`height' to zero.

[PATCH] Add SMP barrier to ipc's grow_ary()
From Dipanker Sarma.
Before setting the ids->entries to the new array, there must be a wmb()
to make sure that the memcpyed contents of the new array are visible
before the new array becomes visible.

[PATCH] reduce CPU cost in loop
balance_dirty_pages() is too expensive to call once-per-page. Use the
ratelimited version.
<akpm@digeo.com>
[PATCH] Expanded bad page handling
The page allocator has traditionally just gone BUG when it sees a page
in a bad state. This is usually due to hardware errors, sometimes
software errors.
I'm proposing that we not go BUG() any more, but print lots (and lots)
of diagnostic info and try to continue.
Might be a bit controversial.

[PATCH] Make inode_ops->setxattr value parameter const
Patch from Andreas Gruenbacher <agruen@suse.de>
The setxattr inode operation is defined like this in 2.4 and 2.5:
int (*setxattr) (struct dentry *dentry, const char *name,
void *value, size_t size, int flags);
the original type of the value parameter was `const void *'; the const
obviously has been lost at some point. The definition should be:
int (*setxattr) (struct dentry *dentry, const char *name,
const void *value, size_t size, int flags);

[PATCH] fix endian problem in ext3 htree code
Patch from Christopher Li <chrisl@vmware.com>
This little patch will fix two place in htree code which
forget the "cpu_to_le16" converting . This bug causes
incorrect record length on PPC.
Thanks Franz for report the problem.

[PATCH] remove a warning from __block_write_full_page()
There is a warning in there to detect when block_write_full_page()
attaches buffers to a blockdev page. This is a bad thing because that
page's blocks may then overlap blocks from a different address_space.
So I disallowed it.
But the message can be triggered when an application is mmapping a
blockdev MAP_SHARED. Apparently INND likes to do this.
So remove the warning.

[PATCH] ext2/ext3 Orlov directory accounting fix
Patch from Stephen Tweedie
"In looking at the fix for the ext3 Orlov double-accounting bug, I
noticed a change to the sb->s_dir_count accounting, restoring a
missing s_dir_count++ when we allocate a new directory.
However, I can't find anywhere in the code where we decrement this
again on directory deletion, neither in ext2 nor in ext3, in 2.4 nor
in 2.5."
Locking is via lock_super().

physical address zero.

[PATCH] Fix busy-wait with writeback to large queues
blk_congestion_wait() is a utility function which various callers use
to throttle themselves to the rate at which the IO system can retire
writes.
The current implementation refuses to wait if no queues are "congested"
(>75% of requests are in flight).
That doesn't work if the queue is so huge that it can hold more than
40% (dirty_ratio) of memory. The queue simply cannot enter congestion
because the VM refuses to allow more than 40% of memory to be dirtied.
(This spin could happen with a lot of normal-sized queues too)
So this patch simply changes blk_congestion_wait() to throttle even if
there are no congested queues. It will cause the caller to sleep until
someone puts back a write request against any queue. (Nobody uses
blk_congestion_wait for read congestion).
The patch adds new state to backing_dev_info->state: a couple of flags
which indicate whether there are _any_ reads or writes in flight
against that queue. This was added to prevent blk_congestion_wait()
from taking a nap when there are no writes at all in flight.
But the "are there any reads" info could be used to defer background
writeout from pdflush, to reduce read-vs-write competition. We'll see.
Because the large request queues have made a fundamental change:
blocking in get_request_wait() has been the main form of VM throttling
for years. But with large queues it doesn't work any more - all
throttling happens in blk_congestion_wait().
Also, change io_schedule_timeout() to propagate the schedule_timeout()
return value. I was using that in some debug code, but it should have
been like that from day one.

[PATCH] Remove mapping->vm_writeback
The vm_writeback address_space operation was designed to provide the VM
with a "clustered writeout" capability. It allowed the filesystem to
perform more intelligent writearound decisions when the VM was trying
to clean a particular page.
I can't say I ever saw any real benefit from this - not much writeout
actually happens on that path - quite a lot of work has gone into
minimising it actually.
The default ->vm_writeback a_op which I provided wrote back the pages
in ->dirty_pages order. But there is one scenario in which this causes
problems - writing a single 4G file with mem=4G. We end up with all of
ZONE_NORMAL full of dirty pages, but all writeback effort is against
highmem pages. (Because there is about 1.5G of dirty memory total).
Net effect: the machine stalls ZONE_NORMAL allocation attempts until
the ->dirty_pages writeback advances onto ZONE_NORMAL pages.
This can be fixed most sweetly with additional radix-tree
infrastructure which will be quite complex. Later.
So this patch dumps it all, and goes back to using writepage
against individual pages as they come off the LRU.

[PATCH] strengthen the `incremental min' logic in the page
Strengthen the `incremental min' logic in the page allocator.
Currently it is allowing the allocation to succeed if the zone has
free_pages >= pages_high.
This was to avoid a lockup corner case in which all the zones were at
pages_high so reclaim wasn't doing anything, but the incremental min
refused to take pages from those zones anyway.
But we want the incremental min zone protection to work. So:
- Only allow the allocator to dip below the incremental min if he
cannot run direct reclaim.
- Change the page reclaim code so that on the direct reclaim path,
the caller can free pages beyond ->pages_high. So if the incremental
min test fails, the caller will go and free some more memory.
Eventually, the caller will have freed enough memory for the
incremental min test to pass against one of the zones.

[PATCH] handle zones which are full of unreclaimable pages
This patch is a general solution to the situation where a zone is full
of pinned pages.
This can come about if:
a) Someone has allocated all of ZONE_DMA for IO buffers
b) Some application is mlocking some memory and a zone ends up full
of mlocked pages (can happen on a 1G ia32 system)
c) All of ZONE_HIGHMEM is pinned in hugetlb pages (can happen on 1G
machines)
We'll currently burn 10% of CPU in kswapd when this happens, although
it is quite hard to trigger.
The algorithm is:
- If page reclaim has scanned 2 * the total number of pages in the
zone and there have been no pages freed in that zone then mark the
zone as "all unreclaimable".
- When a zone is "all unreclaimable" page reclaim almost ignores it.
We will perform a "light" scan at DEF_PRIORITY (typically 1/4096'th of
the zone, or 64 pages) and then forget about the zone.
- When a batch of pages are freed into the zone, clear its "all
unreclaimable" state and start full scanning again. The assumption
being that some state change has come about which will make reclaim
successful again.
So if a "light scan" actually frees some pages, the zone will revert to
normal state immediately.
So we're effectively putting the zone into "low power" mode, and lightly
polling it to see if something has changed.
The code works OK, but is quite hard to test - I mainly tested it by
pinning all highmem in hugetlb pages.

[PATCH] no-buffer-head ext2 option
Implements a new set of block address_space_operations which will never
attach buffer_heads to file pagecache. These can be turned on for ext2
with the `nobh' mount option.
During write-intensive testing on a 7G machine, total buffer_head
storage remained below 0.3 megabytes. And those buffer_heads are
against ZONE_NORMAL pagecache and will be reclaimed by ZONE_NORMAL
memory pressure.
This work is, of course, a special for the huge highmem machines.
Possibly it obsoletes the buffer_heads_over_limit stuff (which doesn't
work terribly well), but that code is simple, and will provide relief
for other filesystems.
It should be noted that the nobh_prepare_write() function and the
PageMappedToDisk() infrastructure is what is needed to solve the
problem of user data corruption when the filesystem which backs a
sparse MAP_SHARED mapping runs out of space. We can use this code in
filemap_nopage() to ensure that all mapped pages have space allocated
on-disk. Deliver SIGBUS on ENOSPC.
This will require a new address_space op, I expect.
