[XFS] Tight loop in xfs_finish_reclaim_all prevented the xfslogd to run
its queue of IO completion callbacks, thus creating the deadlock between umount and xfslogd. Breaking the loop solves the problem. SGI-PV: 943821 SGI-Modid: xfs-linux-melb:xfs-kern:202363a Signed-off-by: Felix Blyakher <felixb@sgi.com> Signed-off-by: Nathan Scott <nathans@sgi.com>
