amt does not need to access struct socket itself in the fast path; it only reads struct sock, and struct socket is only used for tunnel setup and teardown. Let's store struct sock directly in struct amt. amt_dev_stop() is called as dev->netdev_ops->ndo_stop(). synchronize_net() in unregister_netdevice_many_notify() ensures that inflight amt RX fast paths finish before amt_dev is freed. amt no longer needs synchronize_rcu() in udp_tunnel_sock_release(). Note that amt_dev_stop() looks buggy; cancel_delayed_work_sync() should be called after udp_tunnel_sock_release().
