The pages are added to these queues through the NUMA hinting page faults (memory follow CPU algorithm with false sharing evaluation) and knuma_migrated then is waken with a certain hysteresis to migrate the memory in round robin from all remote nodes to its local node. The head that belongs to the local node that knuma_migrated runs on, for now must be empty and it's not being used.
