rps: add __rcu annotations
Add __rcu annotations to : (struct netdev_rx_queue)->rps_map (struct netdev_rx_queue)->rps_flow_table struct rps_sock_flow_table *rps_sock_flow_table; And use appropriate rcu primitives. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
