Relocates the code that notifies users of node subscriptions so that it is adjacent to the rest of the routines that implement TIPC's node subscription capability. Renames the name table routine that is invoked by a node subscription to better reflect its purpose and to be consistent with other, similar name table routines. These changes are cosmetic in nature, and do not alter the behavior of TIPC. Signed-off-by: Allan Stephens <Allan.Stephens@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
