XFS bug in log recover with quota (bugzilla id 855)
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."
