From b3d7e2b29b226c986cbd4efcaf43ab3ff90e6fdb Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 13 Jun 2016 20:21:52 -0700 Subject: [PATCH] net_sched: sch_codel: defer skb freeing in codel_change() codel_change() can use rtnl_qdisc_drop() to defer expensive skb freeing after locks are released. codel_reset() already has support for deferred skb freeing because it uses qdisc_reset_queue() Signed-off-by: Eric Dumazet Signed-off-by: David S.
