From f68cfe2a785edcd25da02cd6124de97f59a5c9c5 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Tue, 26 Jul 2011 09:15:45 +0100 Subject: GFS2: Fix mount hang caused by certain access pattern to sysfs files commit 19237039919088781b4191a00bdc1284d8fea1dd upstream. Depending upon the order of userspace/kernel during the mount process, this can result in a hang without the _all version of the completion.
