There is no need to process outstanding netlink user->kernel packets
during rtnl_unlock now. There is no rtnl_trylock in the rtnetlink_rcv
anymore.
Normal code path is the following:
netlink_sendmsg
netlink_unicast
netlink_sendskb
skb_queue_tail
netlink_data_ready
rtnetlink_rcv
mutex_lock(&rtnl_mutex);
netlink_run_queue(sk, qlen, &rtnetlink_rcv_msg);
mutex_unlock(&rtnl_mutex);
So, it is possible, that packets can be present in the rtnl->sk_receive_queue
during rtnl_unlock, but there is no need to process them at that moment as
rtnetlink_rcv for that packet is pending.
