From f30ab418a1d3c5a8b83493e7d70d6876a74aa0ce Mon Sep 17 00:00:00 2001 From: Jarek Poplawski Date: Thu, 13 Nov 2008 22:56:30 -0800 Subject: pkt_sched: Remove qdisc->ops->requeue() etc. After implementing qdisc->ops->peek() and changing sch_netem into classless qdisc there are no more qdisc->ops->requeue() users. This patch removes this method with its wrappers (qdisc_requeue()), and also unused qdisc->requeue structure. There are a few minor fixes of warnings (htb_enqueue()) and comments btw. The idea to kill ->requeue() and a similar patch were first developed by David S. Miller. Signed-off-by: Jarek Poplawski Signed-off-by: David S.
