On a side note, the check is still incorrect here because you would allow

...but you are right that we should deal with things like
"/reserved-memory-test" properly. It looks like we should compare
against "/reserved-memory/", note the '/' at the end.

You are right, the trailing / should ensure you only match anything under the reserved-memory node.
