To add some context: one of the reasons to include it in the series as
an RFC at the end was to showcase the userspace side of the API and have
a way for people to see how it can be used. Seeing an API in action
provides useful context for reviewing patches.

I think Pasha forgot to add the RFC tags when he created v2, since it is
only meant to be RFC right now and not proper patches.

Correct, I accidently removed RFC from memfd patches in the version. I
will include memfd preservation as RFCv1 in v3 submission.

The point of moving out of tree was also brought up in the live update
call and I agree with Jason's feedback on it. The plan is to drop it
from the series in the next revision, and just leave a reference to it
in the cover letter instead.

 I will drop libluo/luoctl and will add a pointer to an external repo
where they can be accessed from.
