THP startup warnings can become stale

    Details

    • Case:

      Description

      Unlike most (all?) other things that startup warnings warn about, Transparent Hugepages (THP) can be disabled without requiring the mongod to be restarted. This means that a startup warning about /sys/kernel/mm/transparent_hugepage/enabled or /sys/kernel/mm/transparent_hugepage/defrag can become stale, and no longer indicative of an actual problem. It would be useful if this could somehow be handled.
