From 997266a4a02de882de11c7abecad0a3a42ac84b3 Mon Sep 17 00:00:00 2001 From: Kirill Tkhai Date: Wed, 7 Mar 2018 12:39:06 +0300 Subject: [PATCH] net: Convert ip6 tables pernet_operations The pernet_operations: ip6table_filter_net_ops ip6table_mangle_net_ops ip6table_nat_net_ops ip6table_raw_net_ops ip6table_security_net_ops have exit methods, which call ip6t_unregister_table(). ip6table_filter_net_ops has init method registering filter table. Since there must not be in-flight ipv6 packets at the time of pernet_operations execution and since pernet_operations don't send ipv6 packets each other, these pernet_operations are safe to be async.
