From e2cb77db089796f163092326ca25512845df7a3a Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 7 Oct 2015 16:48:38 -0500 Subject: [PATCH] ipv4: Merge ip_local_out and ip_local_out_sk It is confusing and silly hiding a parameter so modify all of the callers to pass in the appropriate socket or skb->sk if no socket is known.
