commit 510792ee29770a38dd409bf2b469ade2fea9eb52
Author: Christoph Hellwig <hch@xxxxxxxxxxxxx>

xfs: optimize the negative xattr caching
Since the addition of file capabilities every write needs to read xattrs to
check if we have any capabilities to clear. In Linux 3.0 Andi Kleen added
a flag to cache the fact that we do not have any attributes on an inode.
Make sure to already mark a file as not having any attributes when reading
it from disk in case it doesn't even have an attribute fork. Based on an
earlier patch from Andi Kleen.

xfs: prevent against ioend livelocks in xfs_file_fsync
We need to take some locks to prevent new ioends from coming in when we wait
for all existing ones to go away. Up to Linux 3.0 that was done using the
i_mutex held by the VFS fsync code, but now that we are called without
it we need to take care of it ourselves. Use the I/O lock instead of
i_mutex just like we do in other places.

xfs: flag all buffers as metadata
Now that REQ_META bios aren't treated specially in the CFQ I/O schedule
anymore, we can tag all buffers as metadata to make blktrace traces more
meaningful. Note that we use buffers also to zero out partial blocks
in the preallocation / hole punching code, and while they operate on
data blocks the zeros written certainly aren't data. I think this case
is borderline metadata enough to not bother special casing it.

fs: take the ACL checks to common code
Replace the ->check_acl method with a ->get_acl method that simply reads an
ACL from disk after having a cache miss. This means we can replace the ACL
checking boilerplate code with a single implementation in namei.c.

vfs: move ACL cache lookup into generic code
This moves logic for checking the cached ACL values from low-level
filesystems into generic code. The end result is a streamlined ACL
check that doesn't need to load the inode->i_op->check_acl pointer at
all for the common cached case.
The filesystems also don't need to check for a non-blocking RCU walk
case in their acl_check() functions, because that is all handled at a
VFS layer.

xfs: Fix wrong return value of xfs_file_aio_write
The fsync prototype change commit 02c24a82187d accidentally overwrote
the ssize_t return value of xfs_file_aio_write with 0 for SYNC type
writes. Fix this by checking if an error occured when calling
xfs_file_fsync and only change the return value in this case.
In addition xfs_file_fsync actually returns a normal negative error, so
fix this, too.

fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlers
Btrfs needs to be able to control how filemap_write_and_wait_range() is called
in fsync to make it less of a painful operation, so push down taking i_mutex and
the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some
file systems can drop taking the i_mutex altogether it seems, like ext3 and
ocfs2. For correctness sake I just pushed everything down in all cases to make
sure that we keep the current behavior the same for everybody, and then each
individual fs maintainer can make up their mind about what to do from there.

fs: move inode_dio_done to the end_io handler
For filesystems that delay their end_io processing we should keep our
i_dio_count until the the processing is done. Enable this by moving
the inode_dio_done call to the end_io handler if one exist. Note that
the actual move to the workqueue for ext4 and XFS is not done in
this patch yet, but left to the filesystem maintainers. At least
for XFS it's not needed yet either as XFS has an internal equivalent
to i_dio_count.

xfs: make use of new shrinker callout for the inode cache
Convert the inode reclaim shrinker to use the new per-sb shrinker
operations. This allows much bigger reclaim batches to be used, and
allows the XFS inode cache to be shrunk in proportion with the VFS
dentry and inode caches. This avoids the problem of the VFS caches
being shrunk significantly before the XFS inode cache is shrunk
resulting in imbalances in the caches during reclaim.
