Subject: [PATCH v3 0/5] A few bugfix and cleanup patches for sbitmap

Hi, this series contain a bugfix patch to correct wake_batch
recalculation to avoid potential IO hung and a few cleanup patches to
remove unnecessary check and repeat code in sbitmap. Thanks.

v3:
 -Thank Jan for review. Collect Reviewed-by from Jan for all patches.
 -some cleanups according to recommends from Jan:
   1)Add Fixes tag in patch 2/5 "sbitmap: remove redundant check in
__sbitmap_queue_get_batch"
   2)Avoid lines over 80 characters in patch 3/5 "sbitmap: rewrite
sbitmap_find_bit_in_index to reduce repeat code"
   3)Remove pointless line in patch 4/5 "sbitmap: add sbitmap_find_bit
to remove repeat code in __sbitmap_get/__sbitmap_get_shallow"
