Subject[PATCH 15/62] ocfs2: Fill node number during cluster stack init
Date
It doesn't make sense to query for a node number before connecting to the
cluster stack. This should be safe to do because node_num is only just
printed,
and we're actually only moving the setting of node num a small amount
further in the mount process.

[ Disconnect when node query fails -- Joel ]
