As mentioned earlier, uapi headers using the __u* types seems not
uncommon. Another aspect is consistency, these types are used throughout
the whole file already, so if I should change them, they all should be
changed. And assuming uapi/linux/tcp.h being a good example: struct
tcp_info uses them also.
