From b04a3d098c4ca176849ee579880c63c052ce6776 Mon Sep 17 00:00:00 2001 From: Kirill Tkhai Date: Mon, 5 Mar 2018 14:32:15 +0300 Subject: net: Convert ctnetlink_net_ops These pernet_operations register and unregister two conntrack notifiers, and they seem to be safe to be executed in parallel. General/not related to async pernet_operations JFI: ctnetlink_net_exit_batch() actions are grouped in batch, and this could look like there is synchronize_rcu() is forgotten. But there is synchronize_rcu() on module exit patch (in ctnetlink_exit()), so this batch may be reworked as simple .exit method. Signed-off-by: Kirill Tkhai Signed-off-by: David S.
