Subject: [PATCHSET v2 0/11] Various block optimizations
Date: Tue, 13 Nov 2018 08:42:22 -0700 [thread overview]
Message-ID: <20181113154233.15256-1-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 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
