So it feels like we should expose this state in e.g. /proc and allow userspace daemons (e.g. systemd, kubelet) to perform idle collection too, even if the system isn't actually low on resources from the kernel's perspective. And doing that requires some sort of kill(pid, SIGKILL_IF_IDLE) or so? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
