Subject: [PATCHSET v6 0/8] Improve async iomap DIO performance
Date: Mon, 24 Jul 2023 16:55:03 -0600 [thread overview]
Message-ID: <20230724225511.599870-1-axboe@kernel.dk> (raw)
Hi,
Hi,
This patchset improves async iomap DIO performance, for XFS and ext4.
For full details on this patchset, see the v4 posting:
https://lore.kernel.org/io-uring/20230720181310.71589-1-axboe@kernel.dk/

No change in performance since last time, and passes my testing without
complaints.
Changes in v6:
- Drop the polled patch, it's not needed anymore
- Change the "inline is safe" logic based on Dave's suggestions
- Gate HIPRI on INLINE_COMP|CALLER_COMP, so polled IO follows the
same rules as inline/deferred completions.
- INLINE_COMP is purely for reads, writes can user CALLER_COMP to
avoid a workqueue punt. This is necessary as we need to invalidate
pages on write completions, and if we race with a buffered reader
or writer on the file.
