Merge branch 'net-sched-taprio-fix-null-pointer-dereference-in-class-dump'
Weiming Shi says:
====================
net/sched: taprio: fix NULL pointer dereference in class dump
Patch 1/2 is the fix: replace NULL entries in q->qdiscs[] with the
global &noop_qdisc singleton so that control-plane dump paths, as well
as the existing NULL guards in the data-plane enqueue/dequeue paths,
cannot deref a NULL child qdisc.
Patch 2/2 is a tdc regression test that drives the graft + delete +
class-dump sequence on a multi-queue netdevsim device. It panics the
vulnerable kernel and passes on the fixed one.
