[RFC 1/3] block: Introduce blk_bio_map_sg() to map one bio

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. Signed-off-by: Baolin Wang --- block/blk-merge.c | 45
