I think that's not possible. You can't query information that 
hasn't been stored.

Your best bet in a Change-Function-Name-Port would probably be to 
use access time and mount the file system with options that won't 
touch that anymore after creation. But me thinks such a solution 
would be rather unreliable and not worth the time investment.
