[PATCH v3 0/5] blk-wbt: simple improvment to enable wbt correctly

[Yu Kuai]

changes in v3:
 - instead of check elevator name, add a flag in elevator_queue, as
 suggested by Christoph.
 - add patch 3 and patch 5 to this patchset.

changes in v2:
 - define new api if wbt config is not enabled in patch 1.

Yu Kuai (5):
  wbt: don't show valid wbt_lat_usec in sysfs while wbt is disabled
  elevator: add new field flags in struct elevator_queue
  block, bfq: don't disable wbt if CONFIG_BFQ_GROUP_IOSCHED is disabled
  blk-wbt: don't enable throttling if default elevator is bfq
  elevator: remove redundant code in elv_unregister_queue()
