From 913a71d250803130eac523e7a2b6439e31a0bc83 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Thu, 6 May 2010 11:03:29 +0100 Subject: GFS2: Add some useful messages The following patch adds a message to indicate when barriers have been disabled due to a block device which doesn't support them. You could already tell this via the mount options in /proc/mounts, but all the other filesystems also log a message at the same time. Also, the same mechanisms are used to indicate when the lock demote interface has been used (only ever used for debugging) which is a request from our support team.
