Subject: [PATCH] xfs: start periodic workers later
Date: Mon, 11 Jul 2011 09:59:57 -0400 [thread overview]
Message-ID: <20110711135957.GA23737@infradead.org> (raw)
Start the periodic sync workers only after we have finished xfs_mountfs
and thus fully set up the filesystem structures. Without this we can
call into xfs_qm_sync before the quotainfo strucute is set up if the
mount takes unusually long, and probably hit other incomplete states
as well.
Also clean up the xfs_fs_fill_super error path by using consistent
label names, and removing an impossible to reach case.
