From 38a424e4657462fe9f8b76f01a0e879abde99ab4 Mon Sep 17 00:00:00 2001 From: David Miller Date: Sun, 1 Jul 2012 02:02:53 +0000 Subject: ipv4: Kill ip_route_input_noref(). The "noref" argument to ip_route_input_common() is now always ignored because we do not cache routes, and in that case we must always grab a reference to the resulting 'dst'. Signed-off-by: David S.
