ocfs2: Abstract out node number queries.
ocfs2 asks the cluster stack for the local node's node number for two reasons; to fill the slot map and to print it. While the slot map isn't necessary for userspace cluster stacks, the printing is very nice for debugging. Thus we add ocfs2_cluster_this_node() as a generic API to get this value. It is anticipated that the slot map will not be used under a userspace cluster stack, so validity checks of the node num only need to exist in the slot map code. Otherwise, it just gets used and printed as an opaque value. [ Fixed up some "int" versus "unsigned int" issues and made osb->node_num truly opaque. --Mark ] Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
