From 8b712cd58adfe6aeeb0be4ecc011dc35620719e7 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Tue, 7 Jul 2009 17:22:12 -0400 Subject: ocfs2: Fixup orphan scan cleanup after failed mount If the mount fails for any reason, ocfs2_dismount_volume calls ocfs2_orphan_scan_stop. It requires that ocfs2_orphan_scan_init be called to setup the mutex and work queues, but that doesn't happen if the mount has failed and we oops accessing an uninitialized work queue. This patch splits the init and startup of the orphan scan, eliminating the oops.
