Honestly, this looks broken to me. multipage-bvec was a big invasive series with a lot of latter fixups. While taking this patch on it's own should be save by itself, but also useless. So if it is needed to make a KASAN warning go away we need to dig deeper and back something else out that should not have been backported to rely on multipage bvec becasue without the other patches they don't exist and can't acually work.
