You would have to modify kernel code to do this; the main question
which comes to mind is *why* would you want to do something like this?
It seems like an ideal problem set that a professor might give to a
student, since it would force them to try to get from an inode to the
pathname used to open the file.  So it seems to be one of these really
pointless things that isn't particularly useful in real life, except
for pedagogical purposes.
