Subject: GFS2: Fix mount hang caused by certain access pattern to sysfs files
From: Steven Whitehouse <[email protected]>
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.
