Subject: [PATCHSET v2 0/11] Various block optimizations
Date: Thu, 15 Nov 2018 12:51:24 -0700 [thread overview]
Message-ID: <20181115195135.22812-1-axboe@kernel.dk> (raw)
Some of these are optimizations, the latter part is prep work
for supporting polling with aio.
Patches against my for-4.21/block branch. These patches can also
be found in my mq-perf branch, though there are other patches
sitting on top of this series (notably aio polling, as mentioned).
Changes since v2:
- Include polled swap IO in the poll optimizations
- Get rid of unnecessary write barrier for DIO wakeup
- Fix a potential stall if need_resched() was set and preempt
wasn't enabled
- Provide separate mq_ops for NVMe with poll queues
- Drop q->mq_ops patch
- Rebase on top of for-4.21/block
Changes since v1:
- Improve nvme irq disabling for polled IO
- Fix barriers in the ordered wakeup for polled O_DIRECT
- Add patch to allow polling to find any command that is done
- Add patch to control whether polling spins or not
- Have async O_DIRECT mark a bio as pollable
- Don't plug for polling
