How? This patch ensures every segment is block size aligned. We can always split a bio in the middle of a bvec for any lower level hardware constraints, and I'm not finding any splitting criteria that would try to break a bio on a non-block aligned boundary.
Do you mean bio_vec with segment here? How do we ensure that?
