I think you should used two different values here for cur and max so
that you can also detect stupid API bugs such as a union being used
instead of a struct, or copy-pastes in the implementation etc. For
example using 1<<20 and 1<<21 should do the trick.

Otherwise Ack-by me for the whole series, of course.

Thanks,
Willy
