From 65d292a2ef2df66fd1ab83447afee71ef3720ded Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 16 Apr 2008 00:55:06 -0700 Subject: [PATCH] [VLAN]: Allow vlan devices registration in net namespaces. This one is similar to what I've done for TUN - set the proper net after device allocation and clean VLANs on net exit (use the rtnl_kill_links helper finally). Plus, drop explicit init_net usage and net != &init_net checks. Signed-off-by: Pavel Emelyanov Acked-by: Patrick McHardy Signed-off-by: David S.
