Hi Jens,
this patch series makes the injection mechanism better at preserving
control on I/O.

Thanks,
Paolo

Paolo Valente (4):
  block, bfq: update inject limit only after injection occurred
  block, bfq: reduce upper bound for inject limit to max_rq_in_driver+1
  block, bfq: increase update frequency of inject limit
  block, bfq: push up injection only after setting service time
