Got a bug report on io_uring that submission time with O_DIRECT rose dramatically once the queue depth got higher. Turns out that __blkdev_direct_IO() does not honor IOCB_NOWAIT at all. blk-mq returns -EAGAIN errors through the bio end_io callback, which isn't super useful for cases where you want

Here's v4 of the io_uring interface. No user visible changes this time, outside of bumping the io_uring_sqe submission entry to a full 64-bytes. This aligns better with caches, and leaves us some room to grow for future features. See the v3 posting for full details on the API: https://lore.kernel.

[PATCH v2 1/2] bcache: writeback rate shouldn't artifically clamp [PATCH v2 2/2] bcache: rearrange writeback main thread ratelimit This is a reroll of the previous "don't clamp" patch. It corrects type issues where negative numbers were handled badly (mostly for display in writeback_rate_debug).

Subject: an iomap-based direct I/O implementation Hi all, this series adds a new direct I/O implementation based on the iomap interface, and switches XFS to use it. The first two patches are a resend of my earlier series to remove the XFS iolock. They are needed for the lockdep assert in the ne
