From 3b1e0a655f8eba44ab1ee2a1068d169ccfb853b9 Mon Sep 17 00:00:00 2001 From: YOSHIFUJI Hideaki Date: Wed, 26 Mar 2008 02:26:21 +0900 Subject: [NET] NETNS: Omit sock->sk_net without CONFIG_NET_NS. Introduce per-sock inlines: sock_net(), sock_net_set() and per-inet_timewait_sock inlines: twsk_net(), twsk_net_set(). Without CONFIG_NET_NS, no namespace other than &init_net exists. Let's explicitly define them to help compiler optimizations.
