changes in v4:
  - remove patch 3 from v3
  - add patch 2,3 in v4

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 (6):
   elevator: remove redundant code in elv_unregister_queue()
   blk-wbt: remove unnecessary check in wbt_enable_default()
   blk-wbt: make enable_state more accurate
   blk-wbt: don't show valid wbt_lat_usec in sysfs while wbt is disabled
   elevator: add new field flags in struct elevator_queue
   blk-wbt: don't enable throttling if default elevator is bfq
