29 * Due the fact that dlm has pre-configured node addresses on every side
35 * application layer. The version field of every node will be set on these RCOM
36 * messages as soon as they arrived and the node isn't yet part of the nodes
47 * compatibility. A node cannot send anything to another node when a DLM_FIN
51 * manager removed the node from internal lists, at this point DLM does not
52 * send any message to the other node. There exists two cases:
160 * We could send a fence signal for a specific node to the cluster
185 /* counts how many lockspaces are using this node
187 * node wants to disconnect.
