OK, Linux v4.4.y LTS has userfaultfd - is affected.

Just anorganizational question:
As this commit has no CC:stable tag, how do release-manager get the
information to include that in their series of patches?

One technical question:
How do I get the latest Linux version shipped userfaultfd first?
( Maybe there exist more elegant ways I do. Always open to improve my
Git knowledge. )
