[XFS] Fix inode size update before data write in xfs_setattr
When changing the file size by a truncate() call, we log the change in the
inode size. However, we do not flush any outstanding data that might not
have been written to disk, thereby violating the data/inode size update
order. This can leave files full of NULLs on crash.
Hence if we are truncating the file, flush any unwritten data that may lie
between the curret on disk inode size and the new inode size that is being
logged to ensure that ordering is preserved.

[XFS] Allow punching holes to free space when at ENOSPC
Make the free file space transaction able to dip into the reserved blocks
to ensure that we can successfully free blocks when the filesystem is at
ENOSPC.

[XFS] Implement ->page_mkwrite in XFS.
Hook XFS up to ->page_mkwrite to ensure that we know about mmap pages
being written to. This allows use to do correct delayed allocation and
ENOSPC checking as well as remap unwritten extents so that they get
converted correctly during writeback. This is done via the generic
block_page_mkwrite code.

commit 5417169026c3df151adf5a65eb061278b0a72e69
Author: David Chinner <[email protected]>
Date: Thu Jul 19 17:39:55 2007 +1000
[FS] Implement block_page_mkwrite.
Many filesystems need a ->page-mkwrite callout to correctly
set up pages that have been written to by mmap. This is especially
important when mmap is writing into holes as it allows filesystems
to correctly account for and allocate space before the mmap
write is allowed to proceed.
Protection against truncate races is provided by locking the page
and checking to see whether the page mapping is correct and whether
it is beyond EOF so we don't end up allowing allocations beyond
the current EOF or changing EOF as a result of a mmap write.
