I'd defer to the maintainers of that code for doing so.
The subsequent ones are independent of this though, so it would
seem possible/reasonable to apply some or all of those that don't
require backports even if the one above doesn't apply cleanly.
Iirc at least the scsiback one might also need a backport, but that
again wouldn't hinder the pciback ones going in.
