Date:	Sun, 20 Jul 2008 14:21:24 +0900 (JST)
From:	YOSHIFUJI Hideaki / 吉藤英明

Cc:	yoshfuji@...ux-ipv6.org, netdev@...r.kernel.org
Subject: [PATCH net-2.6 1/4] netns: Use net_eq() to compare net-namespaces
 for optimization.

Without CONFIG_NET_NS, namespace is always &init_net.
Compiler will be able to omit namespace comparisons with this patch.
