Merge tag 'iomap-5.5-merge-11' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull iomap updates from Darrick Wong: "In this release, we hoisted as much of XFS' writeback code into iomap as was practicable, refactored the unshare file data function, added the ability to perform buffered io copy on write, and tweaked various parts of the directio implementation as needed to port ext4's directio code (that will be a separate pull). Summary: - Make iomap_dio_rw callers explicitly tell us if they want us to wait - Port the xfs writeback code to iomap to complete the buffered io library functions - Refactor the unshare code to share common pieces - Add support for performing copy on write with buffered writes - Other minor fixes - Fix unchecked return in iomap_bmap - Fix a type casting bug in a ternary statement in iomap_dio_bio_actor - Improve tracepoints for easier diagnostic ability - Fix pipe page leakage in directio reads" * tag 'iomap-5.5-merge-11' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (31 commits) iomap: Fix pipe page leakage during splicing iomap: trace iomap_appply results iomap: fix return value of iomap_dio_bio_actor on 32bit systems iomap: iomap_bmap should check iomap_apply return value iomap: Fix overflow in iomap_page_mkwrite fs/iomap: remove redundant check in iomap_dio_rw() iomap: use a srcmap for a read-modify-write I/O iomap: renumber IOMAP_HOLE to 0 iomap: use write_begin to read pages to unshare iomap: move the zeroing case out of iomap_read_page_sync iomap: ignore non-shared or non-data blocks in xfs_file_dirty iomap: always use AOP_FLAG_NOFS in iomap_write_begin iomap: remove the unused iomap argument to __iomap_write_end iomap: better document the IOMAP_F_* flags iomap: enhance writeback error message iomap: pass a struct page to iomap_finish_page_writeback iomap: cleanup iomap_ioend_compare iomap: move struct iomap_page out of iomap.h iomap: warn on inline maps in iomap_writepage_map iomap: lift the xfs writeback code to iomap ...
