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.
