From d57a9212e00779181d8d820887dcab3e9d529194 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Thu, 1 Nov 2007 00:46:50 -0700 Subject: [PATCH] [NET]: Hide the net_ns kmem cache This cache is only required to create new namespaces, but we won't have them in CONFIG_NET_NS=n case. Hide it under the appropriate ifdef. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
