Originally I thought that it was enough to decrease *wbc->range_start to
the ondisk EOF since the _flush_unmap function triggers a writepages
call.  Maybe it's better to make that part explicit.

However, it's only necessary to extend writeback like that if you're
going to retain the delalloc -> written state change.  I don't consider
applying patch 2 to be a good idea though.
