Nope, adding cc:stable is manual, case-by-case and the -stable
maintainers have been asked not to automatically backport MM patches
which contain Fixes:.

So this one snuck into mainline without the cc:stable tag.

Thanks for noticing. Greg, Sasha: can we please add mainline's
85668fda932a ("userfaultfd: verify VMA state across UFFDIO_COPY retry")
to the backporting pile?
