From 9df9e7832391cf699abbf39fc8d95d7e78297462 Mon Sep 17 00:00:00 2001 From: Paul Bolle Date: Mon, 4 Mar 2013 02:45:41 +0000 Subject: [PATCH] netfilter: nfnetlink: silence warning if CONFIG_PROVE_RCU isn't set MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Since commit c14b78e7decd0d1d5add6a4604feb8609fe920a9 ("netfilter: nfnetlink: add mutex per subsystem") building nefnetlink.o without CONFIG_PROVE_RCU set, triggers this GCC warning: net/netfilter/nfnetlink.c:65:22: warning: ‘nfnl_get_lock’ defined but not used [-Wunused-function] The cause of that warning is, in short, that rcu_lockdep_assert() compiles away if CONFIG_PROVE_RCU is not set. Silence this warning by open coding nfnl_get_lock() in the sole place it was called, which allows to remove that function.
