From 757764f61d07ab8ff84699b6d608eac7bc94cecc Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov <xemul@openvz.org> Date: Mon, 24 Mar 2008 14:56:02 -0700 Subject: [PATCH] [NETNS][TCP]: Register /proc/net/tcp in a namespace. After the commit f40c8174d3c21bf178283f3ef3aa8c7bf238fdec ([NETNS][IPV4] tcp - make proc handle the network namespaces) it is now possible to make this file present in newly created namespaces.
