advantages:
* Before, iterating over bios was very awkward when you weren't processing
exactly one bvec at a time - for example, bio_copy_data() in fs/bio.c,
exactly one bvec at a time - for example, bio_copy_data() in block/bio.c,
which copies the contents of one bio into another. Because the biovecs
wouldn't necessarily be the same size, the old code was tricky convoluted -
it had to walk two different bios at the same time, keeping both bi_idx and
