From: Yu Kuai <yukuai3@huawei.com>

Patch 1 print signed value for 'carryover_ios/bytes' to user.

Patch 2 fix that comparation ”unsigned value < negative value“ will
pass, causing that io won't be throttled in the silce.

Patch 3,4 fix that 'carryover_ios/bytes' is not cleared while
'io/bytes_disp' is cleared, causing that throttle is not accurate.

Yu Kuai (4):
  blk-throttle: print signed value 'carryover_bytes/ios' for user
  blk-throttle: fix wrong comparation while 'carryover_ios/bytes' is
    negative
  blk-throttle: use calculate_io/bytes_allowed() for throtl_trim_slice()
  blk-throttle: consider 'carryover_ios/bytes' in throtl_trim_slice()
