360 * Hangup is a hack for tools compatibility. Older ocfs2-tools software
361 * expects the filesystem to call "ocfs2_hb_ctl" during unmount. This
362 * happens regardless of whether the DLM got started, so we can't do it
363 * in ocfs2_cluster_disconnect(). We bring the o2hb_stop() function into
364 * the glue and provide a "hangup" API for super.c to call.
365 *
366 * Other stacks will eventually provide a NULL ->hangup() pointer.
