From 03c05f0d4bb0c267edf12d614025a40e33c5a6f9 Mon Sep 17 00:00:00 2001 From: Jarek Poplawski Date: Fri, 31 Oct 2008 00:46:19 -0700 Subject: pkt_sched: Use qdisc->ops->peek() instead of ->dequeue() & ->requeue() Use qdisc->ops->peek() instead of ->dequeue() & ->requeue() pair. After this patch the only remaining user of qdisc->ops->requeue() is netem_enqueue(). Based on ideas of Herbert Xu, Patrick McHardy and David S. Miller.
