pkt_sched: Add and use qdisc_root() and qdisc_root_lock(). When code wants to lock the qdisc tree state, the logic operation it's doing is locking the top-level qdisc that sits of the root of the netdev_queue. Add qdisc_root_lock() to represent this and convert the easiest cases. In order for this to work out in all cases, we have to hook up the noop_qdisc to a dummy netdev_queue. Signed-off-by: David S.
