In my view the question is: is there any chance, this VFS op routine is 
going to be called outside the LKM unload context. If the answer is true,
then of course the right thing to do is create that VFS op routine.

If we can't come up with an example for this, then I would opt for the LKM
unload cleanup function - but thats just a matter of taste.
