From 2db2d67e4cf6100249bad575d9c13c16fd7b06dc Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 10 Jul 2012 07:03:43 -0700 Subject: [PATCH] ipv4: Kill dst_copy_metrics() call from ipv4_blackhole_route(). Blackhole routes have a COW metrics operation that returns NULL always, therefore this dst_copy_metrics() call did absolutely nothing. Signed-off-by: David S.
