However, *this does not matter*. Let's not get carried away. If container_of() ends up as a compile-time addition of +8, instead of +0, there is not going to be a visible effect in the world.

But other times, they are just pointless to fret about, and this is once such case. thanks, -- John Hubbard NVIDIA
