In dm-crypt, it need to map one bio to scatterlist for improving the hardware engine encryption efficiency. Thus this patch introduces the blk_bio_map_sg() function to map one bio with scatterlists. For avoiding the duplicated code in __blk_bios_map_sg() function, add one parameter to distinguish bio map or request map.
Just detach the bio in blk_bio_map_sg() instead of adding a separate case (and argument) for it in __blk_bios_map_sg().
