Perhaps I did not express it the right way, but
I did not say that this is used somewhere outside the sl*b code.
All I meant is that we return a pointer, like ZERO_SIZE_PTR
that notifies us that we have not allocated anything if a user
wants to access or to free data. This pointers are just for
internal usage of course.
