Here are the two fixes that make sure that iop objects get attached to
pages eventually (in iomap_writepage_map if not earlier), but not too
early (before inline inodes are read).  These are the fixes required for
making gfs2 filesystems with a block size smaller than the page size
work again.

As Christoph has pointed out [*], there are several more cases in which
we can avoid iop creation.  Those improvements are still left to be done.

Thanks,
Andreas

  iomap: Don't create iomap_page objects for inline files
  iomap: Permit pages without an iop to enter writeback
