Why __u64 and not u64?
For consistency as there's `__u32' used elsewhere in this file. It's not clear to me what our rules WRT the use of `s*'/`u*' vs `__s*'/`__u*' are. I don't think we have it mentioned under Documentation/. Please clarify if you know and I can update the change accordingly.
The rule is, AFAICT, use __u*/__s* in user (uapi) headers. Everywhere else, use u*/s*.
Fair enough, that's consistent with ISO C's designation of identifiers whose names start with an underscore as reserved (for system use, etc.).
