If I make a draw by saying that I will go with the "ioctls for enclave
fd" as I'm already making good progress in implementation for v19 and we
will look at it?

Does not look like a fruitful conversation to continue forward without
functional code. I will also update my selftest (as it is part of the
patch set) to align with whatever we have so you can immediately run
something.

And since no one is giving me anything at all on swapping but instead
cutting hairs on here, I will lock in (at least for v19) to use shmem
again.

Sounds like a plan? All the internals will work for whatever mess we
want to introduce to the uapi.
