Message-ID: <20111221134729.3d652e24@nehalam.linuxnetplumber.net>
Date: Wed, 21 Dec 2011 13:47:29 -0800
From: Stephen Hemminger <shemminger@...tta.com>
To: David Miller <davem@...emloft.net>
Cc: netdev@...r.kernel.org
Subject: [PATCH 1/3] netlink: af_netlink cleanup
Don't inline functions that cover several lines, and do inline
the trivial ones. Also make some arguments const.
