  sbitmap: remove unnecessary calculation of alloc_hint in
    __sbitmap_get_shallow
  sbitmap: remove redundant check in __sbitmap_queue_get_batch
  sbitmap: rewrite sbitmap_find_bit_in_index to reduce repeat code
  sbitmap: add sbitmap_find_bit to remove repeat code in
    __sbitmap_get/__sbitmap_get_shallow
