Subject: [PATCH v7 0/2] cancel all throttled bios in del_gendisk()

If del_gendisk() is done when some io are still throttled, such io
will not be handled until the throttle is done, which is not
necessary.

Changes in v7:
 - use the new solution as suggested by Ming.

Yu Kuai (2):
  blk-throtl: introduce a new flag THROTL_TG_CANCELING
  block: cancel all throttled bios in del_gendisk()
