Re: SLUB: Return ZERO_SIZE_PTR for kmalloc(0)

So "ZERO_SIZE_OBJ_PTR" is the most correct form, and "ZERO_SIZE_PTR" is a
convenient shortening. "ZERO_PTR" is too short and also confuses with NULL
because NULL is a zero-value object, rather than a non-zero--value pointer to
a zero-size object.

Like I said, I would prefer NIL of if absolutely need be NIL_PTR. NULL is a pointer that doesn't point anywhere valid -- NIL is a pointer that points to a zero sized object.

If I'd have a few small children around I'd show them the word ZERO_SIZE_PTR and make pictures of them bursting out in tears.
