Yeah but you can pin important pages in RAM with mlock family of syscalls and friends like move_pages for explicit page management. This is what materialize does as far as I understand it.

That seems to be contradictory, as they talk about using it to spill to disk in a simpler way. You can’t swap with mlock?

Also move_pages is about numa nodes not spilling to swap
