Subject: [PATCH BUGFIX IMPROVEMENT 0/8] block, bfq: fix bugs, reduce exec time and boost performance

Hi,
since I didn't make it to submit these ones for 5.1, let me be
early for 5.2 :)

These patches fix some bug affecting performance, reduce execution
time a little bit, and boost throughput and responsiveness.

They are meant to be applied on top of the last series I submitted:
https://lkml.org/lkml/2019/1/29/368

Thanks,
Paolo

Francesco Pollicino (2):
  block, bfq: print SHARED instead of pid for shared queues in logs
  block, bfq: save & resume weight on a queue merge/split

Paolo Valente (6):
  block, bfq: increase idling for weight-raised queues
  block, bfq: do not idle for lowest-weight queues
  block, bfq: tune service injection basing on request service times
  block, bfq: do not merge queues on flash storage with queueing
  block, bfq: do not tag totally seeky queues as soft rt
  block, bfq: always protect newly-created queues from existing active
    queues
