From aee18a8cf28808b7302ef698d77fa73883e60f1b Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Sat, 5 Jul 2008 23:23:27 -0700 Subject: [PATCH] net-sched: sch_htb: remove write-only qdisc filter_cnt The filter_cnt is supposed to count filter references to a class. Since the qdisc can't be the target of a filter, it doesn't need a filter_cnt. In fact the counter is never decreased since cls_api considers a return value of zero a failure and doesn't unbind again. Signed-off-by: Patrick McHardy Signed-off-by: David S.
