Johannes, do you believe this interface is sufficient to induce memcg based reclaim or do you have plans to propose a memory.reclaim extension to memcg?
I assume that lru_gen could be used even if memcg is disabled whereas memory.reclaim would only be available on systems where the controller is mounted through cgroups.
Yet a question would probably arise about the stability of this interface since it lives in debugfs: can we plan on /sys/kernel/debug/lru_gen being long-term supported?
