net: Queue net_cleanup_work only if there is first net added When llist_add() returns false, cleanup_net() hasn't made its llist_del_all(), while the work has already been scheduled by the first queuer. So, we may skip queue_work() in this case. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>
