From d8f44c335a1111d647f41e9fa6ae65b18db112e4 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Mon, 21 Sep 2015 13:02:43 -0500 Subject: [PATCH] ipvs: Pass ipvs into .conn_schedule and ip_vs_try_to_schedule This moves the hack "net_ipvs(skb_net(skb))" up one level where it will be easier to remove.
