From 4a1c537113cdc688aabc3fb9bb6ed18ec821c779 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 12 Sep 2007 11:56:32 +0200 Subject: [PATCH] [NET]: Add a network namespace tag to struct net_device Please note that network devices do not increase the count count on the network namespace. The are inside the network namespace and so the network namespace tag is in the nature of a back pointer and so getting and putting the network namespace is unnecessary. Signed-off-by: Eric W.
