I am checking my own patch ... :)
looks like this function is not doing anything. its just getting the lock,
traversing the list, unlocking and returning.
I am guessing by the function name that the function was supposed to free
something.

Greg - please drop this series. I will try to find if something can be
freed else I will remove this function.
