From 9d6dda32c7570bbf189cf74fbc36338d0a94e999 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Mon, 15 Oct 2007 12:55:33 -0700 Subject: [PATCH] [NETNS]: Don't panic on creating the namespace's loopback When the loopback device is failed to initialize inside the new namespaces, panic() is called. Do not do it when the namespace in question is not the init_net. Plus cleanup the error path a bit. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
