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. :("
