96f951edb1 Add #includes needed to permit the removal of asm/system.h
asm/system.h is a cause of circular dependency problems because it contains
commonly used primitive stuff like barrier definitions and uncommonly used
stuff like switch_to() that might require MMU definitions.

asm/system.h has been disintegrated by this point on all arches into the
following common segments:

 (1) asm/barrier.h

     Moved memory barrier definitions here.

 (2) asm/cmpxchg.h

     Moved xchg() and cmpxchg() here.  #included in asm/atomic.h.

 (3) asm/bug.h

     Moved die() and similar here.

 (4) asm/exec.h

     Moved arch_align_stack() here.

 (5) asm/elf.h

     Moved AT_VECTOR_SIZE_ARCH here.

 (6) asm/switch_to.h

     Moved switch_to() here.

69e1aaddd6 Ext4 commits for 3.3 merge window; mostly cleanups and bug fixes
The changes to export dirty_writeback_interval are from Artem's s_dirt
 cleanup patch series.  The same is true of the change to remove the
 s_dirt helper functions which never got used by anyone in-tree.  I've
 run these changes by Al Viro, and am carrying them so that Artem can
 more easily fix up the rest of the file systems during the next merge
 window.  (Originally we had hopped to remove the use of s_dirt from
 ext4 during this merge window, but his patches had some bugs, so I
 ultimately ended dropping them from the ext4 tree.)

b18dafc86b vfs: fix d_ancestor() case in d_materialize_unique
In d_materialise_unique() there are 3 subcases to the 'aliased dentry'
case; in two subcases the inode i_lock is properly released but this
does not occur in the -ELOOP subcase.

This seems to have been introduced by commit 1836750115f2 ("fix loop
checks in d_materialise_unique()").

Cc: stable@vger.kernel.org # v3.0+
[ Added a comment, and moved the unlock to where we generate the -ELOOP,
  which seems to be more natural.

  You probably can't actually trigger this without a buggy network file
  server - d_materialize_unique() is for finding aliases on non-local
  filesystems, and the d_ancestor() case is for a hardlinked directory
  loop.

  But we should be robust in the case of such buggy servers anyway. ]

d97d32edcd xfs: Fix oops on IO error during xlog_recover_process_iunlinks()
When an IO error happens during inode deletion run from
xlog_recover_process_iunlinks() filesystem gets shutdown. Thus any subsequent
attempt to read buffers fails. Code in xlog_recover_process_iunlinks() does not
count with the fact that read of a buffer which was read a while ago can
really fail which results in the oops on
  agi = XFS_BUF_TO_AGI(agibp);

Fix the problem by cleaning up the buffer handling in
xlog_recover_process_iunlinks() as suggested by Dave Chinner. We release buffer
lock but keep buffer reference to AG buffer. That is enough for buffer to stay
pinned in memory and we don't have to call xfs_read_agi() all the time.

a66d636385 xfs: fix fstrim offset calculations
xfs_ioc_fstrim() doesn't treat the incoming offset and length
correctly. It treats them as a filesystem block address, rather than
a disk address. This is wrong because the range passed in is a
linear representation, while the filesystem block address notation
is a sparse representation. Hence we cannot convert the range direct
to filesystem block units and then use that for calculating the
range to trim.

While this sounds dangerous, the problem is limited to calculating
what AGs need to be trimmed. The code that calcuates the actual
ranges to trim gets the right result (i.e. only ever discards free
space), even though it uses the wrong ranges to limit what is
trimmed. Hence this is not a bug that endangers user data.

Fix this by treating the range as a disk address range and use the
appropriate functions to convert the range into the desired formats
for calculations.

Further, fix the first free extent lookup (the longest) to actually
find the largest free extent. Currently this lookup uses a <=
lookup, which results in finding the extent to the left of the
largest because we can never get an exact match on the largest
extent. This is due to the fact that while we know it's size, we
don't know it's location and so the exact match fails and we move
one record to the left to get the next largest extent. Instead, use
a >= search so that the lookup returns the largest extent regardless
of the fact we don't get an exact match on it.

4a5e98f5d6 Btrfs: improve the logic in btrfs_can_relocate()
Currently if we don't have enough space allocated we go ahead and loop
though devices in the hopes of finding enough space for a chunk of the
*same* type as the one we are trying to relocate.  The problem with that
is that if we are trying to restripe the chunk its target type can be
more relaxed than the current one (eg require less devices or less
space).  So, when restriping, run checks against the target profile
instead of the current one.

0c460c0d70 Btrfs: move alloc_profile_is_valid() to volumes.c
Header file is not a good place to define functions.  This also moves a
call to alloc_profile_is_valid() down the stack and removes a redundant
check from __btrfs_alloc_chunk() - alloc_profile_is_valid() takes it
into account.

e8920a640b Btrfs: make profile_is_valid() check more strict
"0" is a valid value for an on-disk chunk profile, but it is not a valid
extended profile.  (We have a separate bit for single chunks in extended
case)

Also rename it to alloc_profile_is_valid() for clarity.

e3176ca276 Btrfs: stop silently switching single chunks to raid0 on balance
This has been causing a lot of confusion for quite a while now and a lot
of users were surprised by this (some of them were even stuck in a
ENOSPC situation which they couldn't easily get out of).  The addition
of restriper gives users a clear choice between raid0 and drive concat
setup so there's absolutely no excuse for us to keep doing this.

7a3ae2f8c8 Btrfs: fix regression in scrub path resolving
In commit 4692cf58 we introduced new backref walking code for btrfs. This
assumes we're searching live roots, which requires a transaction context.
While scrubbing, however, we must not join a transaction because this could
deadlock with the commit path. Additionally, what scrub really wants to do
is resolving a logical address in the commit root it's currently checking.

This patch adds support for logical to path resolving on commit roots and
makes scrub use that.

The two helper functions commit_cowonly_roots() and
create_pending_snapshot() failed to check the return value from
btrfs_cow_block(), which could at least in theory fail with -ENOSPC from
btrfs_alloc_free_block(). This commit adds the missing checks.

it did never hurt we forgot to actually call it. This turns our lockdep
identifier strings from lockdep auto-set #[id] into really pretty

ea46679408 Btrfs: deal with read errors on extent buffers differently
Since we need to read and write extent buffers in their entirety we can't use
the normal bio_readpage_error stuff since it only works on a per page basis.  So
instead make it so that if we see an io error in endio we just mark the eb as
having an IO error and then in btree_read_extent_buffer_pages we will manually
try other mirrors and then overwrite the bad mirror if we find a good copy.
This works with larger than page size blocks.  Thanks,

a6c22850d2 jffs2: update to new MTD interface
There were a few instances of the old MTD interface remaining for JFFS2. We
fix one error that shows up (only when CONFIG_JFFS2_FS_WRITEBUFFER is not
defined) like this:

  fs/jffs2/read.c: In function 'jffs2_read_dnode':
  fs/jffs2/read.c:36:8: error: 'struct mtd_info' has no member named 'read'
  fs/jffs2/read.c:112:8: error: 'struct mtd_info' has no member named 'read'
  ...

We also simply remove two macros that are not in use, were not updated to
the new MTD interface, and don't even utilize the old interface properly.
(That means they weren't used since commit 8593fbc6, year 2006; almost 6
years ago, for those who don't want to do the math)
