568 * @divs: the layout specification on which the scatterlist will be based
569 * @alignmask: the algorithm's alignmask
570 * @total_len: the total length of the scatterlist to build in bytes
571 * @data: if non-NULL, the buffers will be filled with this data until it ends.
572 * Otherwise the buffers will be poisoned. In both cases, some bytes
573 * past the end of each buffer will be poisoned to help detect overruns.
574 * @out_divs: if non-NULL, the test_sg_division to which each scatterlist entry
575 * corresponds will be returned here. This will match @divs except
576 * that divisions resolving to a length of 0 are omitted as they are
577 * not included in the scatterlist.
