[Ocfs2-devel] [patch 1/3] ocfs2-expose-o2nm_cluster.patch

[abeekhof@suse.de <abeekhof@suse.de>]

From: Andrew Beekhof <abeekhof@suse.de>
Subject: [patch 1/3] OCFS2 - Expose struct o2nm_cluster 

Subsequent patches (namely userspace heartbeat and configurable timeouts)
require access to the o2nm_cluster struct.  This patch does the necessary
shuffling.

Signed-off-by: Andrew Beekhof <abeekhof@suse.de>
