From 163cd4e817a4444e348ca577cb74c71d245f0c72 Mon Sep 17 00:00:00 2001 From: Duan Jiong Date: Fri, 9 May 2014 13:31:43 +0800 Subject: [PATCH] ipv6: remove parameter rt from fib6_prune_clones() the parameter rt will be assigned to c.arg in function fib6_clean_tree(), but function fib6_prune_clone() doesn't use c.arg, so we can remove it safely.
