These pernet_operations register and unregister net::ipv4.iptable_filter table. Since there are no packets in-flight at the time of exit method is working, iptables rules should not be touched. Also, pernet_operations should not send ipv4 packets each other. So, it's safe to mark them async. Signed-off-by: NKirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: NDavid S.
