From: Paul Bolle Date: Mon, 4 Mar 2013 02:45:41 +0000 (+0000) Subject: netfilter: nfnetlink: silence warning if CONFIG_PROVE_RCU isn't set X-Git-Tag: v3.9-rc3~36^2~25^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9df9e7832391cf699abbf39fc8d95d7e78297462;p=pandora-kernel.git netfilter: nfnetlink: silence warning if CONFIG_PROVE_RCU isn't set 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.
