      rbd: don't zero-fill non-image object requests · 6e2a4505
      Alex Elder authored
      A result of ENOENT from a read request for an object that's part of
      an rbd image indicates that there is a hole in that portion of the
      image.  Similarly, a short read for such an object indicates that
      the remainder of the read should be interpreted a full read with
      zeros filling out the end of the request.
      
      This behavior is not correct for objects that are not backing rbd
      image data.  Currently rbd_img_obj_request_callback() assumes it
      should be done for all objects.
      
      Change rbd_img_obj_request_callback() so it only does this zeroing
      for image objects.  Encapsulate that special handling in its own
      function.  Add an assertion that the image object request is a bio
      request, since we assume that (and we currently don't support any
      other types).
      
      This resolves a problem identified here:
