Now some cipher hardware engines prefer to handle bulk block by merging requests to increase the block size and thus increase the hardware engine processing speed. This patchset introduces request bulk mode to help the crypto hardware drivers improve in efficiency. Changes since v1: - Modify the sg_is_contiguous() function.
