the per_chunk_alignment is just a bool which says that each chunk has to start at an aligned address. get_alignement() seems to be used to align the chunk size. It might come from gf-complete' strange alignment requirements. Instead of requiring aligned buffers it requires that src and dst buffer have the same remainder when divided by 16. The best way to archieve that is to align the length to 16 and use a single buffer. I agree it's convoluted.
