But there is one, rather major issue: we're crossing kernel-userspace
boundary. And with the scheme we'll have to cross the boundary four times:

Query-and-control scheme looks very attractive, and that's actually
resembles my balance level idea, when userland tells the kernel how much

The main characteristics are the same to what I've tried to add to vmevent
API:
Internally, it uses Mel Gorman's idea of scanned/reclaimed ratio for
pressure index calculation. But we don't expose the index to the

So I'm thinking that a better design
