Message-Id: <1461332394-3994-19-git-send-email-pablo@netfilter.org>
Date: Fri, 22 Apr 2016 15:39:49 +0200
From: Pablo Neira Ayuso <pablo@...filter.org>
To: netfilter-devel@...r.kernel.org
Cc: davem@...emloft.net, netdev@...r.kernel.org
Subject: [PATCH 18/23] netfilter: ctnetlink: remove unnecessary inlining
Many of these functions are called from control plane path. Move
ctnetlink_nlmsg_size() under CONFIG_NF_CONNTRACK_EVENTS to avoid a
compilation warning when CONFIG_NF_CONNTRACK_EVENTS=n.
