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@xxxxxxxxx/ Darrick, if you want to queue this up, that works for me. Risk of conflict on the io_uring side is small. Changes in v5: - Collect reviews - Rename IOCB_DIO_DEFER to IOCB_DIO_CALLER_COMP - Rename IOMAP_DIO_DEFER_COMP to IOMAP_DIO_CALLER_COMP - Improve some comments based on Darrick's feedback - Rename IOMAP_DIO_STABLE_WRITE to IOMAP_DIO_WRITE_THROUGH - Add patch making the IOMAP_DIO_* defines unsigned -- Jens Axboe
