From 16c6a4f24de2933b26477ad5dfb71f518220d641 Mon Sep 17 00:00:00 2001 From: Joel Becker Date: Tue, 19 Jun 2007 11:34:03 -0700 Subject: 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.
