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.
