Message-Id: <1442365458-16349-5-git-send-email-ebiederm@xmission.com>
Date: Tue, 15 Sep 2015 20:03:53 -0500
From: "Eric W. Biederman" <ebiederm@...ssion.com>
To: Pablo Neira Ayuso <pablo@...filter.org>,
David Miller <davem@...emloft.net>
Cc: netfilter-devel@...r.kernel.org, <netdev@...r.kernel.org>
Subject: [PATCH next 05/30] net: Merge dst_output and dst_output_sk
Add a sock paramter to dst_output making dst_output_sk superfluous.
Add a skb->sk parameter to all of the callers of dst_output
Have the callers of dst_output_sk call dst_output.
Signed-off-by: "Eric W. Biederman" <ebiederm@...ssion.com>
