XFS bug in log recover with quota (bugzilla id 855)
commit 8ec6dba2581754e375be66f7bedd708d856d8b30 upstream.
Hi,
I was hit by a bug in linux 2.6.31 when XFS is not able to recover the
log after a crash if fs was mounted with quotas. Gory details in XFS
bugzilla: http://oss.sgi.com/bugzilla/show_bug.cgi?id=855.
It looks like wrong struct is used in buffer length check, and the following
patch should fix the problem.
xfs_dqblk_t has a size of 104+32 bytes, while xfs_disk_dquot_t is 104 bytes
long, and this is exactly what I see in system logs - "XFS: dquot too small
(104) in xlog_recover_do_dquot_trans."
