From: Yu Kuai <yukuai3@xxxxxxxxxx> 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() block/blk-throttle.c | 105 +++++++++++++++++++++---------------------- block/blk-throttle.h | 4 +- 2 files changed, 54 insertions(+), 55 deletions(-) -- 2.39.2
