I agree the reclaim-reporting granularity mismatch could be a room to improve. As I also mentioned on my previous reply, this was one of the main motivations of Access/Contiguity-aware Memory Autoscaling [1] proposal. As also mentioned on the previous reply, the project made no much progress yet, though. [1] https://lore.kernel.org/all/[email protected]/ Thanks, SJ [...]
