4. MADV_DEMOTE and MADV_PROMOTE provide a better balance between capacity and latency. They allow hot pages that need promoting to be promoted smoothly and pages that need demoting to be demoted immediately. This helps tiered memory systems to operate more rationally.Can you summarize why something similar could not be provided by a library that builds up on existing functionality, such as migrate_pages?
Sorry, I actually wanted to refer to "move_pages", not "migrate_pages". -- Cheers, David / dhildenb
