Message-ID: <20111123121251.GB6348@secunet.com>
Date: Wed, 23 Nov 2011 13:12:51 +0100
From: Steffen Klassert <steffen.klassert@...unet.com>
To: David Miller <davem@...emloft.net>
Cc: netdev@...r.kernel.org
Subject: [PATCH 2/5] net: Rename the dst_opt default_mtu method to mtu
We plan to invoke the dst_opt->default_mtu() method unconditioally
from dst_mtu(). So rename the method to dst_opt->mtu() to match
the name with the new meaning.
