Subject: [PATCH 0/2] Fix inode reclaim problems (hopefully)
Date: Thu,  7 Jan 2010 10:05:23 +1100	[thread overview]
Message-ID: <1262819125-27083-1-git-send-email-david@fromorbit.com> (raw)

These two patches seem to fix the inode reclaim issues I've been
able to reproduce lately. The changes are still running xfsqa in a
loop to confirm this, but the directory/small file stress test I've
been running to trigger the problem has run for 10 hours with these
fixes instead of dying after 20-30 minutes.

The first patch is a rewrite of Christoph's reclaim under write lock
fixes without all the code duplication, and the second avoids direct
reclaim altogether because xfs_inode_clean() needs to be run when the
flush lock is held to ensure the inode not under IO and really is
reclaimable.
