I assume some Documentation/ is forthcoming.

Consuming another page flag hurts. What's our current status there?

I'd be interested in seeing some usage examples. Perhaps anecdotes
where "we observed problem X so we used memdelay in manner Y and saw
result Z".

I assume that some userspace code which utilizes this interface exists
already. What's the long-term plan here? systemd changes?
