From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Subject: [PATCH] netns: move {inc,dec}_net_namespaces into #ifdef Date: Fri, 23 Sep 2016 18:06:12 +0200 Message-ID: <20160923160650.3631870-1-arnd@arndb.de> Cc: Arnd Bergmann , "Eric W. Biederman" , WANG Cong , netdev@vger.kernel.org, linux-kernel@vger.kernel.org To: "David S. Miller" Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org 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.
