From 8608db031b4d2932d645709e2cfe8fbcd91a7305 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 18 Aug 2008 20:51:18 -0700 Subject: pkt_sched: Never schedule non-root qdiscs. Based upon initial discovery and patch by Jarek Poplawski. The qdisc watchdogs can be attached to any qdisc, not just the root, so make sure we schedule the correct one. CBQ has a similar bug.
