From a6254864c08109c66a194612585afc0439005286 Mon Sep 17 00:00:00 2001 From: Duan Jiong Date: Mon, 17 Feb 2014 15:23:43 +0800 Subject: [PATCH] ipv4: fix counter in_slow_tot since commit 89aef8921bf("ipv4: Delete routing cache."), the counter in_slow_tot can't work correctly. The counter in_slow_tot increase by one when fib_lookup() return successfully in ip_route_input_slow(), but actually the dst struct maybe not be created and cached, so we can increase in_slow_tot after the dst struct is created.
