Thanks SJ for the reviews.
I will address all of the changes in the next revision. The only thing over here is, I would
like the filter to work for folios of all sizes, even PAGE_SIZE. It would give us a more convenient
way of knowing if hot regions are mainly being backed by 4K pages, and improve observability.
Let me know if thats ok?
