From 6b2cf618cc8445a03640d1e5e36829352e297017 Mon Sep 17 00:00:00 2001 From: Felix Blyakher Date: Fri, 25 Nov 2005 16:42:13 +1100 Subject: [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.
