Ying Xue 7b8613e0a1 tipc: fix a potential deadlock ... Locking dependency detected below possible unsafe locking scenario: CPU0 CPU1 T0: tipc_named_rcv() tipc_rcv() T1: [grab nametble write lock]* [grab node lock]* T2: tipc_update_nametbl() tipc_node_link_up() T3: tipc_nodesub_subscribe() tipc_nametbl_publish() T4: [grab node lock]* [grab nametble write lock]* The opposite order of holding nametbl write lock and node lock on above two different paths may result in a deadlock. If we move the the updating of the name table after link state named out of node lock, the reverse order of holding locks will be eliminated, and as a result, the deadlock risk.
