[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> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
