    Here is another set of small code tidy-ups:
        - Define SECTOR_SHIFT and SECTOR_SIZE, and use these symbolic
          names throughout.  Tell the blk_queue system our physical
          block size, in the (unlikely) event we want to use something
          other than the default.
        - Delete the definition of struct rbd_info, which is never used.
        - Move the definition of dev_to_rbd() down in its source file,
          just above where it gets first used, and change its name to
          dev_to_rbd_dev().
        - Replace an open-coded operation in rbd_dev_release() to use
          dev_to_rbd_dev() instead.
        - Calculate the segment size for a given rbd_device just once in
          rbd_init_disk().
        - Use the '%zd' conversion specifier in rbd_snap_size_show(),
          since the value formatted is a size_t.
        - Switch to the '%llu' conversion specifier in rbd_snap_id_show().
          since the value formatted is unsigned.
