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 v2: - move WARN_ON_ONCE() from throtl_rb_first() to it's caller - merge some patches into one.
Changes in v3: - some code optimization in patch 1 - hold queue lock to cancel bios in patch 2
Yu Kuai (2): blk-throtl: move WARN_ON_ONCE() from throtl_rb_first() to it's caller block: cancel all throttled bios in del_gendisk()
