SubjectRe: [patch 5/7] make netfilter use strict integer types

I _strongly disagree_ with this move. Userspace also has the uintX
types via <stdint.h>/<cstdint>, and now you are adding a dependency
on linux/types.h, not to mention that your step can lead to compile
time piling up.

IMHO, __uXX should be replaced by uintX_t, but a move this great I
will leave to future generations because there is just too much
persisting opinions wrt. such proposal. As such I'd like to join
and persist on my position and that uintX that we have should be kept.
