Subject: Re: [PATCH v8 1/4] blk-throttle: fix that io throttle can only work for single bio
Date: Tue, 23 Aug 2022 08:07:08 -1000 [thread overview]
Message-ID: <YwUXTL+8E/sPcEUB@slm.duckdns.org> (raw)

Hello,
Should have asked you earlier but with the BIO_THROTTLED flag setting from
clone removed, with single BIO_THROTTLED flag, does the fix still require
bytes subtraction? If we can do single flag and we don't need the bytes
subtraction, might as well just stay with single flag?
Thanks.
