Let's forget > configfs here. If it's just for testing, you're right, we probably shouldn't go to the trouble of making a new interface. At the same time, we shouldn't put something in /sys or configfs that we're not committed to, long-term. So, not to replace the memory probe file, but _only_ to drive the new debug-only node hot-add, I think its appropriate place is debugfs. -- Dave -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
