The fixing patch #1 was intended to fix only one issue shown in the
warnings: qdisc_watchdog scheduled leaf qdiscs for qdisc_run(), so
they were dequeued directly (skipping root qdiscs) and with wrong
locks.
The fixing patch #2 changes qdisc locking generally, so it probably
fixed other locking issues btw. like this last oops seen after the
patch #1. But still there is this (not critical) issue of skipping
root qdiscs while dequeuing after qdisc_watchdog, which has to be done
by the fixing patch #1.
