6b3286ed11 [PATCH] rename struct namespace to struct mnt_namespace
Rename 'struct namespace' to 'struct mnt_namespace' to avoid confusion with
other namespaces being developped for the containers : pid, uts, ipc, etc.
'namespace' variables and attributes are also renamed to 'mnt_ns'

Replace all uses of kmem_cache_t with struct kmem_cache.

The patch was generated using the following script:

	#!/bin/sh
	#
	# Replace one string by another in all the kernel sources.
	#

	set -e

	for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do
		quilt add $file
		sed -e "1,\$s/$1/$2/g" $file >/tmp/$$
		mv /tmp/$$ $file
		quilt refresh
	done

The script was run like this

	sh replace kmem_cache_t "struct kmem_cache"

d2c89a4284 [PATCH] reiserfs: reset errval after initializing bitmap cache
Callers after reiserfs_init_bitmap_cache() expect errval to contain -EINVAL
until much later.  If a condition fails before errval is reset later,
reiserfs_fill_super() will mistakenly return 0, causing an Oops in
do_add_mount().  This patch resets errval to -EINVAL after the call.

I view this as a temporary fix and real error codes should be used
throughout reiserfs_fill_super().

edc666e2ff [PATCH] ReiserFS: Make sure all dentries refs are released before calling kill_block_super()
Make sure all dentries refs are released before calling kill_block_super()
so that the assumption that generic_shutdown_super() can completely destroy
the dentry tree for there will be no external references holds true.

What was being done in the put_super() superblock op, is now done in the
kill_sb() filesystem op instead, prior to calling kill_block_super().

Changes made in [try #2]:

 (*) reiserfs_kill_sb() now checks that the superblock FS info pointer is set
     before trying to dereference it.

5065227b46 [PATCH] reiserfs: on-demand bitmap loading
This is the patch the three previous ones have been leading up to.

It changes the behavior of ReiserFS from loading and caching all the bitmaps
as special, to treating the bitmaps like any other bit of metadata and just
letting the system-wide caches figure out what to hang on to.

Buffer heads are allocated on the fly, so there is no need to retain pointers
to all of them.  The caching of the metadata occurs when the data is read and
updated, and is considered invalid and uncached until then.

I needed to remove the vs-4040 check for performing a duplicate operation on a
particular bit.  The reason is that while the other sites for working with
bitmaps are allowed to schedule, is_reusable() is called from do_balance(),
which will panic if a schedule occurs in certain places.

The benefit of on-demand bitmaps clearly outweighs a sanity check that depends
on a compile-time option that is discouraged.

6f01046b35 [PATCH] reiserfs: reorganize bitmap loading functions
This patch moves the bitmap loading code from super.c to bitmap.c

The code is also restructured somewhat.  The only difference between new
format bitmaps and old format bitmaps is where they are.  That's a two liner
before loading the block to use the correct one.  There's no need for an
entirely separate code path.

The load path is generally the same, with the pattern being to throw out a
bunch of requests and then wait for them, then cache the metadata from the
contents.

Again, like the previous patches, the purpose is to set up for later ones.

Update: There was a bug in the previously posted version of this that resulted
in corruption.  The problem was that bitmap 0 on new format file systems must
be treated specially, and wasn't.  A stupid bug with an easy fix.

This is hopefully the last fix for the disaster that is the reiserfs bitmap
patch set.

If a bitmap block was full, first_zero_hint would end up at zero since it
would never be changed from it's zeroed out value.  This just sets it
beyond the end of the bitmap block.  If any bits are freed, it will be
reset to a valid bit.  When info->free_count = 0, then we already know it's
full.

e1fabd3ccf [PATCH] reiserfs: fix is_reusable bitmap check to not traverse the bitmap info array
There is a check in is_reusable to determine if a particular block is a bitmap
block.  It verifies this by going through the array of bitmap block buffer
heads and comparing the block number to each one.

Bitmap blocks are at defined locations on the disk in both old and current
formats.  Simply checking against the known good values is enough.

This is a trivial optimization for a non-production codepath, but this is the
first in a series of patches that will ultimately remove the buffer heads from
that array.

5c81a4197d [PATCH] lockdep: annotate the quota code
The quota code plays interesting games with the lock ordering; to quote Jan:

| i_mutex of inode containing quota file is acquired after all other
| quota locks. i_mutex of all other inodes is acquired before quota
| locks. Quota code makes sure (by resetting inode operations and
| setting special flag on inode) that noone tries to enter quota code
| while holding i_mutex on a quota file...

The good news is that all of this special case i_mutex grabbing happens in the
(per filesystem) low level quota write function.  For this special case we
need a new I_MUTEX_* nesting level, since this just entirely outside any of
the regular VFS locking rules for i_mutex.  I trust Jan on his blue eyes that
this is not ever going to deadlock; and based on that the patch below is what
it takes to inform lockdep of these very interesting new locking rules.

The new locking rule for the I_MUTEX_QUOTA nesting level is that this is the
deepest possible level of nesting for i_mutex, and that this only should be
used in quota write (and possibly read) function of filesystems.  This makes
the lock ordering of the I_MUTEX_* levels:

I_MUTEX_PARENT -> I_MUTEX_CHILD -> I_MUTEX_NORMAL -> I_MUTEX_QUOTA

Has no effect on non-lockdep kernels.

726c334223 [PATCH] VFS: Permit filesystem to perform statfs with a known root dentry
Give the statfs superblock operation a dentry pointer rather than a superblock
pointer.

This complements the get_sb() patch.  That reduced the significance of
sb->s_root, allowing NFS to place a fake root there.  However, NFS does
require a dentry to use as a target for the statfs operation.  This permits
the root in the vfsmount to be used instead.

linux/mount.h has been added where necessary to make allyesconfig build
successfully.

Interest has also been expressed for use with the FUSE and XFS filesystems.

454e2398be [PATCH] VFS: Permit filesystem to override root dentry on mount
Extend the get_sb() filesystem operation to take an extra argument that
permits the VFS to pass in the target vfsmount that defines the mountpoint.

The filesystem is then required to manually set the superblock and root dentry
pointers.  For most filesystems, this should be done with simple_set_mnt()
which will set the superblock pointer and then set the root dentry to the
superblock's s_root (as per the old default behaviour).

The get_sb() op now returns an integer as there's now no need to return the
superblock pointer.

This patch permits a superblock to be implicitly shared amongst several mount
points, such as can be done with NFS to avoid potential inode aliasing.  In
such a case, simple_set_mnt() would not be called, and instead the mnt_root
and mnt_sb would be set directly.

The patch also makes the following changes:

 (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount
     pointer argument and return an integer, so most filesystems have to change
     very little.

 (*) If one of the convenience function is not used, then get_sb() should
     normally call simple_set_mnt() to instantiate the vfsmount. This will
     always return 0, and so can be tail-called from get_sb().

 (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the
     dcache upon superblock destruction rather than shrink_dcache_anon().

     This is required because the superblock may now have multiple trees that
     aren't actually bound to s_root, but that still need to be cleaned up. The
     currently called functions assume that the whole tree is rooted at s_root,
     and that anonymous dentries are not the roots of trees which results in
     dentries being left unculled.

     However, with the way NFS superblock sharing are currently set to be
     implemented, these assumptions are violated: the root of the filesystem is
     simply a dummy dentry and inode (the real inode for '/' may well be
     inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries
     with child trees.

     [*] Anonymous until discovered from another tree.

 (*) The documentation has been adjusted, including the additional bit of
     changing ext2_* into foo_* in the documentation.

4b6a9316fa [PATCH] cpuset memory spread: slab cache filesystems
Mark file system inode and similar slab caches subject to SLAB_MEM_SPREAD
memory spreading.

If a slab cache is marked SLAB_MEM_SPREAD, then anytime that a task that's
in a cpuset with the 'memory_spread_slab' option enabled goes to allocate
from such a slab cache, the allocations are spread evenly over all the
memory nodes (task->mems_allowed) allowed to that task, instead of favoring
allocation on the node local to the current cpu.

The following inode and similar caches are marked SLAB_MEM_SPREAD:

The choice of which slab caches to so mark was quite simple.  I marked
those already marked SLAB_RECLAIM_ACCOUNT, except for fs/xfs, dentry_cache,
inode_cache, and buffer_head, which were marked in a previous patch.  Even
though SLAB_RECLAIM_ACCOUNT is for a different purpose, it marks the same
potentially large file system i/o related slab caches as we need for memory
spreading.

Given that the rule now becomes "wherever you would have used a
SLAB_RECLAIM_ACCOUNT slab cache flag before (usually the inode cache), use
the SLAB_MEM_SPREAD flag too", this should be easy enough to maintain.
Future file system writers will just copy one of the existing file system
slab cache setups and tend to get it right without thinking.

 The ReiserFS code is a mix of a number of different coding styles, sometimes
 different even from line-to-line. Since the code has been relatively stable
 for quite some time and there are few outstanding patches to be applied, it
 is time to reformat the code to conform to the Linux style standard outlined
 in Documentation/CodingStyle.

 This patch contains the result of running scripts/Lindent against
 fs/reiserfs/*.c and include/linux/reiserfs_*.h. There are places where the
 code can be made to look better, but I'd rather keep those patches separate
 so that there isn't a subtle by-hand hand accident in the middle of a huge
 patch. To be clear: This patch is reformatting *only*.

 A number of patches may follow that continue to make the code more consistent
 with the Linux coding style.

 Hans wasn't particularly enthusiastic about these patches, but said he
 wouldn't really oppose them either.

2949ccf937 [PATCH] reiserfs: enable attrs by default if saf
The following patch enables attrs by default if the reiserfs_attrs_cleared
bit is set in the superblock.  This allows chattr-type attrs to be used
without any further action by the user.

f359b74c80 [PATCH] reiserfs: max_key fix
This patch fixes a bug introduced by Al Viro's patch: [patch 136/174]
reiserfs endianness: clone struct reiserfs_key

The problem is MAX_KEY and MAX_IN_CORE_KEY defined in this patch do not
look equal from reiserfs comp_key's point of view.  This caused reiserfs'
sanity check to complain.

6b9f5829e6 [PATCH] reiserfs endianness: comp_short_keys() cleanup
comp_short_keys() massaged into sane form, which kills the last place where
pointer to in_core_key (or any object containing such) would be cast to or
from something else.  At that point we are free to change layout of
in_core_key - nothing depends on it anymore.

So we drop the mess with union in there and simply use (unconditional) __u64
k_offset and __u8 k_type instead; places using in_core_key switched to those.
That gives _far_ better code than current mess - on all platforms.

struct reiserfs_key cloned; (currently) identical struct in_core_key added.
Places that expect host-endian data in reiserfs_key switched to in_core_key.
Basically, we get annotation of reiserfs_key users and keep the resulting tree
obviously equivalent to original.

9a3bb30173 [PATCH] reiserfs: make resize option auto-get new device size
It's trivial for the resize option to auto-get the underlying device size,
while it's harder for the user.  I've copied the code from jfs.

Since of the different reiserfs option parser (which does not use the
superior match_token used by almost every other filesystem), I've had to
use the "resize=auto" and not "resize" option to specify this behaviour.
Changing the option parser to the kernel one wouldn't be bad but I've no
time to do this cleanup in this moment.

Btw, the mount(8) man page should be updated to include this option.  Cc
the relevant people, please (I hope I cc'ed the right people).

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
