Medium term goal is to implement "tc qdisc show" without needing
to acquire RTNL.

This first series makes the requested changes in 14 qdisc.

Eric Dumazet (14):
  net_sched: sch_fq: implement lockless fq_dump()
  net_sched: cake: implement lockless cake_dump()
  net_sched: sch_cbs: implement lockless cbs_dump()
  net_sched: sch_choke: implement lockless choke_dump()
  net_sched: sch_codel: implement lockless codel_dump()
  net_sched: sch_tfs: implement lockless etf_dump()
  net_sched: sch_ets: implement lockless ets_dump()
  net_sched: sch_fifo: implement lockless __fifo_dump()
  net_sched: sch_fq_codel: implement lockless fq_codel_dump()
  net_sched: sch_fq_pie: implement lockless fq_pie_dump()
  net_sched: sch_hfsc: implement lockless accesses to q->defcls
  net_sched: sch_hhf: implement lockless hhf_dump()
  net_sched: sch_pie: implement lockless pie_dump()
  net_sched: sch_skbprio: implement lockless skbprio_dump()
