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.
