Subject: [PATCH 2/3] [IPV6]: inet6_dev on loopback should be kept until namespace stop.
Date: Tue, 18 Mar 2008 17:35:24 +0300	[thread overview]
Message-ID: <1205850925-11736-2-git-send-email-den@openvz.org> (raw)
In-Reply-To: <1205850761.9163.21.camel-aPCOdVxUTlgvJsYlp49lxw@public.gmane.org>

In the other case it will be destroyed when last address will be removed
from lo inside a namespace. This will break IPv6 in several places. The
most obvious one is ip6_dst_ifdown.
