I like it (having just argued for it), except for the __s* and __u*. The ABI definitions aren't for kernel programmers. They are for userspace programmers. So we should use standard types, even if they are a bit ugly (and uint16_t isn't really much uglier than __u16, and at least it doesn't carry connotations of something that is meant to be internal, which is what the standard double-underscore convention means).
Please, let us agree that the ABI definition should use standard types wherever possible.
