      xfs: fix attr2 vs large data fork assert · 4c393a60
      由 Christoph Hellwig 提交于 
      With Dmitry fsstress updates I've seen very reproducible crashes in
xfs_attr_shortform_remove because xfs_attr_shortform_bytesfit claims that
the attributes would not fit inline into the inode after removing an
attribute.  It turns out that we were operating on an inode with lots
of delalloc extents, and thus an if_bytes values for the data fork that
is larger than biggest possible on-disk storage for it which utterly
confuses the code near the end of xfs_attr_shortform_bytesfit.

Fix this by always allowing the current attribute fork, like we already
do for the attr1 format, given that delalloc conversion will take care
for moving either the data or attribute area out of line if it doesn't
fit at that point - or making the point moot by merging extents at this
point.

Also document the function better, and clean up some loose bits.

      xfs: force buffer writeback before blocking on the ilock in inode reclaim · 4dd2cb4a
      由 Christoph Hellwig 提交于 
      If we are doing synchronous inode reclaim we block the VM from making
progress in memory reclaim.  So if we encouter a flush locked inode
promote it in the delwri list and wake up xfsbufd to write it out now.
Without this we can get hangs of up to 30 seconds during workloads hitting
synchronous inode reclaim.

The scheme is copied from what we do for dquot reclaims.

      MAINTAINERS: update XFS maintainer entry · c8891329
      由 Alex Elder 提交于 
      I will no longer be maintaining XFS for SGI.  Ben Myers
(bpm@sgi.com) has agreed to be the primary maintainer
for XFS in my place.  I will continue to be able to push
commits to the SGI XFS tree if required.  As such I will
continue to be a designated XFS maintainer, but plan to
serve in more of a backup role.

      xfs: use doalloc flag in xfs_qm_dqattach_one() · db3e74b5
      由 Mitsuo Hayasaka 提交于 
      The doalloc arg in xfs_qm_dqattach_one() is a flag that indicates
whether a new area to handle quota information will be allocated
if needed. Originally, it was passed to xfs_qm_dqget(), but has
been removed by the following commit (probably by mistake):

	commit 8e9b6e7f
	Author: Christoph Hellwig <hch@lst.de>
	Date:   Sun Feb 8 21:51:42 2009 +0100

	xfs: remove the unused XFS_QMOPT_DQLOCK flag

As the result, xfs_qm_dqget() called from xfs_qm_dqattach_one()
never allocates the new area even if it is needed.

This patch gives the doalloc arg to xfs_qm_dqget() in
xfs_qm_dqattach_one() to fix this problem.
