Message

Changes since V1:
Modified patch 1 and 3 to make the changes more concise, without
introducing additional logic changes.

The patchset mainly address the update logic of tg->[bytes/io]_disp and add
related overflow checks. The last patch also simplified the process.

Zizhi Wo (3):
  blk-throttle: Fix wrong tg->[bytes/io]_disp update in
    __tg_update_carryover()
  blk-throttle: Delete unnecessary carryover-related fields from
    throtl_grp
  blk-throttle: Add an additional overflow check to the call
    calculate_bytes/io_allowed
