Hi, 

Ocfs2 uses configfs to do user-space configuration tasks. When thread
mount.ocfs2 writes fd to /sys/kernel/config/cluster/{clustername}/heartbeat/{region_name}/dev,
kernel will trigger the callback. you can find the source code in
function o2cb_create_heartbeat_region() in ocfs2-tools package.

Thanks.
