Merge tag 'vfs-7.1-rc1.integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfsPull vfs integrity updates from Christian Brauner: "This adds support to generate and verify integrity information (aka T10 PI) in the file system, instead of the automatic below the covers support that is currently used. The implementation is based on refactoring the existing block layer PI code to be reusable for this use case, and then adding relatively small wrappers for the file system use case. These are then used in iomap to implement the semantics, and wired up in XFS with a small amount of glue code. Compared to the baseline this does not change performance for writes, but increases read performance up to 15% for 4k I/O, with the benefit decreasing with larger I/O sizes as even the baseline maxes out the device quickly on my older enterprise SSD"* tag 'vfs-7.1-rc1.integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: xfs: support T10 protection information iomap: support T10 protection information iomap: support ioends for buffered reads iomap: add a bioset pointer to iomap_read_folio_ops ntfs3: remove copy and pasted iomap code iomap: allow file systems to hook into buffered read bio submission iomap: only call into ->submit_read when there is a read_ctx iomap: pass the iomap_iter to ->submit_read iomap: refactor iomap_bio_read_folio_range block: pass a maxlen argument to bio_iov_iter_bounce block: add fs_bio_integrity helpers block: make max_integrity_io_size public block: prepare generation / verification helpers for fs usage block: add a bdev_has_integrity_csum helper block: factor out a bio_integrity_setup_default helper block: factor out a bio_integrity_action helper List of files: /linux/block/bio-integrity-fs.c
