Hi, this series contain some patches to improve in-service queue
preemption, protect max_budget updating race between configuration
and auto-tuning and so on. More details can be found in respective
log message. Thanks!

Kemeng Shi (17):
  block, bfq: properly mark bfqq remained idle
  block, bfq: try preemption if bfqq has higher weight and the same
    priority class
  block, bfq: only preempt plugged in_service_queue if
    bfq_better_to_idle say no
  block, bfq: recover the "service hole" if enough budget is left
  block, bfq: Update bfqd->max_budget with bfqd->lock held
  block, bfq: correct bfq_max_budget and bfq_min_budget
  block, bfq: correct interactive weight-raise check in
    bfq_set_budget_timeout
  block, bfq: start service_from_wr accumulating of async queues
    correctly
  block, bfq: stop to detect queue as waker queue if it already is now
  block, bfq: fix typo in comment
  block, bfq: simpfy computation of bfqd->budgets_assigned
  block, bfq: define and use soft_rt, in_burst and wr_or_deserves_wr
    only low_latency is enable
  block, bfq: remove unnecessary "wr" part of wr_or_deserves_wr
  block, bfq: remove redundant oom_bfqq check for bfqq from
    bfq_find_close_cooperator
  block, bfq: some cleanups for function bfq_pos_tree_add_move
  block, bfq: remove unnecessary goto tag in __bfq_weights_tree_remove
