Joel Becker 16c6a4f24d ocfs2: live heartbeat depends on the local node configuration
Removing the local node configuration out from underneath a running
heartbeat is "bad".  Provide an API in the ocfs2 nodemanager to request
a configfs dependancy on the local node, then use it in heartbeat.

Joel Becker 14829422be ocfs2: Depend on configfs heartbeat items.
ocfs2 mounts require a heartbeat region.  Use the new configfs_depend_item()
facility to actually depend on them so they can't go away from under us.

First, teach cluster/nodemanager.c to depend an item on the o2cb subsystem.
Then teach o2hb_register_callbacks to take a UUID and depend on the
appropriate region.  Finally, teach all users of o2hb to pass a UUID or
NULL if they don't require a pin.

Eric W. Biederman 0e03036c97 [PATCH] sysctl: register the ocfs2 sysctl numbers
ocfs2 was did not have the binary number it uses under CTL_FS registered in
sysctl.h.  Register it to avoid future conflicts, and change the name of the
definition to be in line with the rest of the sysctl numbers.

Andrew Beekhof 296b75ed6a [patch 1/3] OCFS2 - Expose struct o2nm_cluster
Subsequent patches (namely userspace heartbeat and configurable timeouts)
require access to the o2nm_cluster struct.  This patch does the necessary
shuffling.
