Subject: [PATCHSET v2 0/5] Alloc batch fixes
Date: Thu, 4 Nov 2021 09:21:59 -0600 [thread overview]
Message-ID: <20211104152204.57360-1-axboe@kernel.dk> (raw)
Hi,
A few fixes related to the batched allocations:
- Have the requests hold a queue reference, flush them on schedule
unplug as well.
- Make sure the queue matches, could be a mismatch if we're driving
multiple devices.
Since v1:
- Reshuffle series to do plug rq alloc helper before enter changes
- Protect submit_bio_checks() by queue enter reference as well
