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 <serge.hallyn@canonical.com> Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
