From d727abcb2355566a3372ee1810f156fba75112b7 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 14 Jun 2012 02:16:42 -0700 Subject: netns: Deduplicate and fix copy_net_ns when !CONFIG_NET_NS The copy of copy_net_ns used when the network stack is not built is broken as it does not return -EINVAL when attempting to create a new network namespace. We don't even have a previous network namespace. Since we need a copy of copy_net_ns in net/net_namespace.h that is available when the networking stack is not built at all move the correct version of copy_net_ns from net_namespace.c into net_namespace.h Leaving us with just 2 versions of copy_net_ns. One version for when we compile in network namespace suport and another stub for all other occasions. Acked-by: Serge Hallyn Signed-off-by: Eric W.
