Merge tag 'iomap-5.9-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull iomap updates from Darrick Wong: "The most notable changes are: - iomap no longer invalidates the page cache when performing a direct read, since doing so is unnecessary and the old directio code doesn't do that either. - iomap embraced the use of returning ENOTBLK from a direct write to trigger falling back to a buffered write since ext4 already did this and btrfs wants it for their port. - iomap falls back to buffered writes if we're doing a direct write and the page cache invalidation after the flush fails; this was necessary to handle a corner case in the btrfs port. - Remove email virus scanner detritus that was accidentally included in yesterday's pull request. Clearly I need(ed) to update my git branch checker scripts. :(" * tag 'iomap-5.9-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: iomap: fall back to buffered writes for invalidation failures xfs: use ENOTBLK for direct I/O to buffered I/O fallback iomap: Only invalidate page cache pages on direct IO writes iomap: Make sure iomap_end is called after iomap_begin
