Christoph Hellwig <hch@lst.de> says: This series contains the iomap prep work to support zoned XFS. The biggest changes are: - an option to reuse the ioend code for direct writes in addition to the current use for buffered writeback, which allows the file system to track completions on a per-bio basis instead of the current end_io callback which operates on the entire I/O. Note that it might make sense to split the ioend code from buffered-io.c into its own file with this. Let me know what you think of that and I can include it in the next version - change of the writeback_ops so that the submit_bio call can be done by the file system. Note that btrfs will also need this eventually when it starts using iomap - helpers to split ioend to the zone append queue_limits that plug into the previous item above. - a new ANON_WRITE flags for writes that don't have a block number assigned to them at the iomap level, leaving the file system to do that work in the submission handler. Note that btrfs wants something similar also for compressed I/O, which should be able to reuse this, maybe with minor tweaks. - passing private data to a few more helper The XFS changes to use this will be posted to the xfs list only to not spam fsdevel too much. * patches from https://lore.kernel.org/r/20250206064035.2323428-2-hch@lst.de: iomap: pass private data to iomap_truncate_page iomap: pass private data to iomap_zero_range iomap: pass private data to iomap_page_mkwrite iomap: add a io_private field to struct iomap_ioend iomap: optionally use ioends for direct I/O iomap: factor out a iomap_dio_done helper iomap: move common ioend code to ioend.c iomap: split bios to zone append limits in the submission handlers iomap: add a IOMAP_F_ANON_WRITE flag iomap: simplify io_flags and io_type in struct iomap_ioend iomap: allow the file system to submit the writeback bios Link: https://lore.kernel.org/r/20250206064035.2323428-2-hch@lst.de Signed-off-by: Christian Brauner <brauner@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
