[PATCH net v1 0/6] topology server fixes for nametable soft lockup

[Parthasarathy Bhuvaragan <parthasarathy.bhuvaragan@ericsson.com>]

In this series, we revert the commit 333f796235a527 ("tipc: fix a
race condition leading to subscriber refcnt bug") and provide an
alternate solution to fix the race conditions in commits 2-4.

We have to do this as the above commit introduced a nametbl soft
lockup at module exit as described by patch#4.

Parthasarathy Bhuvaragan (6):
  tipc: fix nametbl_lock soft lockup at node/link events
  tipc: add subscription refcount to avoid invalid delete
  tipc: fix connection refcount error
  tipc: fix nametbl_lock soft lockup at module exit
  tipc: ignore requests when the connection state is not CONNECTED
  tipc: fix cleanup at module unload
