From c06bcbfa1ed8daaeb2a262f372b411207891e229 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Thu, 13 May 2010 22:14:53 +0200 Subject: ocfs2: Fix lock inversion in quotas during umount We cannot cancel delayed work from ocfs2_local_free_info because that is called with dqonoff_mutex held and the work it cancels requires dqonoff_mutex to finish. Cancel the work before acquiring dqonoff_mutex.
