From a192069c576cd7d4b7174f26af27950b0a95d269 Mon Sep 17 00:00:00 2001 From: Kirill Tkhai Date: Mon, 22 Oct 2018 20:46:53 +0200 Subject: net: Convert ip_set_net_ops These pernet_operations initialize and destroy net_generic(net, ip_set_net_id)-related data. Since ip_set is under CONFIG_IP_SET, it's easy to watch drivers, which depend on this config. All of them are in net/netfilter/ipset directory, except of net/netfilter/xt_set.c. There are no more drivers, which use ip_set, and all of the above don't register another pernet_operations. Also, there are is no indirect users, as header file include/linux/netfilter/ipset/ip_set.h does not define indirect users by something like this: #ifdef CONFIG_IP_SET extern func(void); #else static inline func(void); #endif So, there are no more pernet operations, dereferencing net_generic(net, ip_set_net_id). ip_set_net_ops are OK to be executed in parallel for several net, so we mark them as async.
