From 13da199c38ee7f33a1c42db62647118f9f9f527c Mon Sep 17 00:00:00 2001 From: Kirill Tkhai Date: Tue, 13 Feb 2018 12:29:13 +0300 Subject: [PATCH] net: Convert subsys_initcall() registered pernet_operations from net/sched psched_net_ops only creates and destroyes /proc entry, and safe to be executed in parallel with any foreigh pernet_operations. tcf_action_net_ops initializes and destructs tcf_action_net::egdev_ht, which is not touched by foreign pernet_operations. So, make them async. Signed-off-by: Kirill Tkhai Acked-by: Andrei Vagin Signed-off-by: David S.
