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. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
