Merge tag 'iomap-6.0-merge-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull more iomap updates from Darrick Wong:
 "In the past 10 days or so I've not heard any ZOMG STOP style
  complaints about removing ->writepage support from gfs2 or zonefs, so
  here's the pull request removing them (and the underlying fs iomap
  support) from the kernel:

   - Remove iomap_writepage and all callers, since the mm apparently
     never called the zonefs or gfs2 writepage functions"

* tag 'iomap-6.0-merge-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
  iomap: remove iomap_writepage
  zonefs: remove ->writepage
  gfs2: remove ->writepage
  gfs2: stop using generic_writepages in gfs2_ail1_start_one
