net: Convert tcpv6_net_ops
These pernet_operations create and destroy net::ipv6.tcp_sk socket, which is used in tcp_v6_send_response() only. It looks like foreign pernet_operations don't want to set ipv6 connection inside destroyed net, so this socket may be created in destroyed in parallel with anything else. inet_twsk_purge() is also safe for that, as described in patch for tcp_sk_ops. So, it's possible to mark them as async. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>
