Subject: [PATCH 0/5] A few cleanup and bugfix patches for sbitmap

Hi, this series contain a patch to fix protential wakup lost in

  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
