Message-Id: <6ca95420a71ea6973c4d42cdbf54f5802d0846e5.1363885020.git.tgraf@suug.ch>
Date: Thu, 21 Mar 2013 18:45:29 +0100
From: Thomas Graf <tgraf@...g.ch>
To: davem@...emloft.net
Cc: netdev@...r.kernel.org
Subject: [PATCH net-next 2/2] rtnetlink: Remove passing of attributes into rtnl_doit functions
With decnet converted, we can finally get rid of rta_buf and its
computations around it. It also gets rid of the minimal header
length verification since all message handlers do that explicitly
anyway.
Signed-off-by: Thomas Graf <tgraf@...g.ch>
