From 2ed6afdee798658fe3c33b50c4a79d1bde45f1d8 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 23 Sep 2016 18:06:12 +0200 Subject: netns: move {inc,dec}_net_namespaces into #ifdef With the newly enforced limit on the number of namespaces, we get a build warning if CONFIG_NETNS is disabled: net/core/net_namespace.c:273:13: error: 'dec_net_namespaces' defined but not used [-Werror=unused-function] net/core/net_namespace.c:268:24: error: 'inc_net_namespaces' defined but not used [-Werror=unused-function] This moves the two added functions inside the #ifdef that guards their callers.
