net: Convert ip6_frags_ops
Exit methods calls inet_frags_exit_net() with global ip6_frags as argument. So, after we make the pernet_operations async, a pair of exit methods may be called to iterate this hash table. Since there is inet_frag_worker(), which already may work in parallel with inet_frags_exit_net(), and it can make the same cleanup, that inet_frags_exit_net() does, it's safe. So we may mark these pernet_operations as async. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>
