From ac7100ba93428a26cde8e47dfcfcfbfbfcce66de Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 14 Feb 2011 19:02:23 +0000 Subject: [PATCH] sch_mqprio: Always set num_tc to 0 in mqprio_destroy() All the cleanup code in mqprio_destroy() is currently conditional on priv->qdiscs being non-null, but that condition should only apply to the per-queue qdisc cleanup. We should always set the number of traffic classes back to 0 here.
