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 <redacted> --- net/sched/act_api.c | 1 + net/sched/sch_api.c | 1 + 2 files changed, 2 insertions(+)
