From 846f40455276617275284a4b76b89311b4aed0b9 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Thu, 16 Dec 2010 15:18:48 +0000 Subject: [PATCH] GFS2: Don't flush delete workqueue when releasing the transaction lock There is no requirement to flush the delete workqueue before a gfs2 filesystem is suspended. The workqueue's work will just be suspended along with the rest of the tasks on the filesystem. The resolves a deadlock situation where the transaction lock's demotion code was trying to flush the delete workqueue while at the same time, the workqueue was waiting for the transaction lock. The delete workqueue is flushed by gfs2_make_fs_ro() already, so that umount/remount are correctly protected anyway.
