I wonder why something closer to the LRU used for the page cache wouldn't be used for determining which tier a page belongs in? It kind of seems like the same problem.

Top-tier memory management
I’m not sure of the precise cost of the mechanisms being proposed here, but the page cache LRU is kind of expensive (at least to me as an FS developer optimizing throughput). I’m not sure that kind of management is appropriate for all of memory. (But I might be off in terms of scale.)
