From cfc069d3fa24d7c6357e3b731e97f94db495bf0c Mon Sep 17 00:00:00 2001 From: Sunil Mushran Date: Tue, 14 Dec 2010 14:14:31 -0800 Subject: ocfs2/cluster: Pin the local node when o2hb thread starts The patch pins the node item of the local node when the o2hb thread starts and unpins on stop. An earlier patch pinned the node item of the remote node on o2net connect and unpinned on disconnect.
