From c346dca10840a874240c78efe3f39acf4312a1f2 Mon Sep 17 00:00:00 2001 From: YOSHIFUJI Hideaki Date: Tue, 25 Mar 2008 21:47:49 +0900 Subject: [NET] NETNS: Omit net_device->nd_net without CONFIG_NET_NS. Introduce per-net_device inlines: dev_net(), dev_net_set(). Without CONFIG_NET_NS, no namespace other than &init_net exists. Let's explicitly define them to help compiler optimizations.
