Hello Guys,
Commit 4f1e9630afe6 ("blk-throtl: optimize IOPS throttle for large IO
scenarios")
only fixes iops throttle for blk-mq drivers. This patchset adds API of
resubmit_bio_noacct
so that we can use it for fixing the same issue on bio based drivers.
Meantime fix the issue on device mapper via the added API, and the issue
is reported by lining.
