From 93d230fe0762bf129fb4debc944af3e1c1e8f40e Mon Sep 17 00:00:00 2001 From: Kirill Tkhai Date: Tue, 13 Feb 2018 12:27:13 +0300 Subject: [PATCH] net: Convert sysctl_pernet_ops This patch starts to convert pernet_subsys, registered from core initcalls. Methods sysctl_net_init() and sysctl_net_exit() initialize net::sysctls table of a namespace. pernet_operations::init()/exit() methods from the rest of the list do not touch net::sysctls of strangers, so it's safe to execute sysctl_pernet_ops's methods in parallel with any other pernet_operations.
