Would be possible to use for threshold pointed value(s) e.g. according to enum zone_state_item, because kinds of memory to track could be different?
E.g. to tracking paging activity NR_ACTIVE_ANON and NR_ACTIVE_FILE could be interesting, not only free.

That seems like a horrible idea, because there is no guarantee that
the kernel will continue to use NR_ACTIVE_ANON and NR_ACTIVE_FILE
internally in the future.

What is exported to userspace must be somewhat independent of the
specifics of how the kernel implements things internally.
