net: remove synchronize_net() from netdev_set_master()
In the old days, we used to access dev->master in __netif_receive_skb() in a rcu_read_lock section. So one synchronize_net() call was needed in netdev_set_master() to make sure another cpu could not use old master while/after we release it. We now use netdev_rx_handler infrastructure and added one synchronize_net() call in bond_release()/bond_release_all() Remove the obsolete synchronize_net() from netdev_set_master() and add one in bridge del_nbp() after its netdev_rx_handler_unregister() call. This makes enslave -d a bit faster. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Jiri Pirko <jpirko@redhat.com> CC: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.
