Subject: [PATCH 13/14][VLAN]: Allows vlan devices registration in net namespace.
Date: Thu, 10 Apr 2008 19:22:15 +0400 [thread overview]
Message-ID: <47FE30A7.4020503@openvz.org> (raw)
In-Reply-To: <47FE2AD4.9080609@openvz.org>
This one is similar to what I've done for TUN - set the proper
net after device allocation and clean VLANs on net exit.
Plus, drop explicit init_net usage.
