The existing interface could be extended with a flags field as part of
the opcode passed in argument 2, which is currently reserved, and then
return a FD, just like seccomp(2) does.  So it is not like the current
patches couldn't be extended in the future if needed, unless I'm
mistaken.

Yes, I'd prefer this series go in as-is, and if there is a need for
extending the API, arg2 can have more values added.

I agree.
