From f07fed82ad7994cc4d779ee79bdf7a46848c4b8f Mon Sep 17 00:00:00 2001 From: WANG Cong Date: Sat, 13 Aug 2016 22:34:56 -0700 Subject: [PATCH] net_sched: remove the leftover cleanup_a() After refactoring tc_action into tcf_common, we no longer need to cleanup temporary "actions" in list, they are permanently stored in the hashtable.
