Your description doesn't include why we need new vmevent_fd(2).
Of course, it's very flexible and potential to add new VM knob easily but
the thing we is about to use now is only VMEVENT_ATTR_PRESSURE.
Is there any other use cases for swap or free? or potential user?
Adding vmevent_fd without them is rather overkill.

What ABI would you use instead?

be maintained forever once we add it.

Agreed.
