From 721499e8931c5732202481ae24f2dfbf9910f129 Mon Sep 17 00:00:00 2001 From: YOSHIFUJI Hideaki Date: Sat, 19 Jul 2008 22:34:43 -0700 Subject: 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. Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S.
