From 4ebdfba73c09d8568d891bae87c40fad43dd7f41 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 7 Oct 2015 16:48:36 -0500 Subject: [PATCH] dst: Pass a sk into .local_out For consistency with the other similar methods in the kernel pass a struct sock into the dst_ops .local_out method. Simplifying the socket passing case is needed a prequel to passing a struct net reference into .local_out. Signed-off-by: "Eric W. Biederman" Signed-off-by: David S.
