Subject[PATCH 4.4 093/101] ocfs2: o2hb: revert hb threshold to keep compatible
4.4-stable review patch.  If anyone has any objections, please let me know.


From: Junxiao Bi <>

commit 33496c3c3d7b88dcbe5e55aa01288b05646c6aca upstream.

Configfs is the interface for ocfs2-tools to set configure to kernel and
$configfs_dir/cluster/$clustername/heartbeat/dead_threshold is the one
used to configure heartbeat dead threshold. Kernel has a default value
of it but user can set O2CB_HEARTBEAT_THRESHOLD in /etc/sysconfig/o2cb
to override it.

Commit 45b997737a80 ("ocfs2/cluster: use per-attribute show and store
methods") changed heartbeat dead threshold name while ocfs2-tools did
not, so ocfs2-tools won't set this configurable and the default value is
always used. So revert it.

Fixes: 45b997737a80 ("ocfs2/cluster: use per-attribute show and store methods")
