Merge branch 'for-linus' of git://oss.sgi.com/xfs/xfs

* 'for-linus' of git://oss.sgi.com/xfs/xfs:
  xfs: fix ->write_inode return values
  xfs: fix xfs_mark_inode_dirty during umount
  xfs: deprecate the nodelaylog mount option
parents b79c4f75 58d84c4e
......@@ -592,3 +592,11 @@ Why: In 3.0, we can now autodetect internal 3G device and already have
interface that was used by acer-wmi driver. It will replaced by
information log when acer-wmi initial.
Who: Lee, Chun-Yi <jlee@novell.com>
----------------------------
What: The XFS nodelaylog mount option
When: 3.3
Why: The delaylog mode that has been the default since 2.6.39 has proven
stable, and the old code is in the way of additional improvements in
the log code.
