From 3b8118cffad224415c6f6f35abe7ca2a1d79c05a Mon Sep 17 00:00:00 2001 From: Kurt Hackel Date: Wed, 17 Jan 2007 17:05:53 -0800 Subject: ocfs2_dlm: Calling post handler function in assert master handler This patch prevents the dlm from sending the clear refmap message before the set refmap. We use the newly created post function handler routine to accomplish the task.
