The patch titled
Subject: ocfs2: pass ocfs2_cluster_connection to ocfs2_this_node
has been removed from the -mm tree. Its filename was
pass-ocfs2_cluster_connection-to-ocfs2_this_node.patch
This patch was dropped because an updated version will be merged
------------------------------------------------------
From: Goldwyn Rodrigues <rgoldwyn@xxxxxxx>
Subject: ocfs2: pass ocfs2_cluster_connection to ocfs2_this_node
This is done to differentiate between using and not using controld and use
the connection information accordingly. We need to be backward
compatible. So, we use a new enum ocfs2_connection_type to identify when
controld is used and when it is not.
