I'm not sure going the whole big struct thing is really necessary, and for an additional reason: this is only meant to be used with the vDSO function, which is also coupled with the kernel. It doesn't return information that's made to be used (or allowed to be used) anywhere else. So both the vdso code and the syscall code are part of the same basic thing that will evolve together. So I'm not convinced extensible struct really makes sense for this, as neat as it is. If there's wide consensus that it's desirable, in contrast to what I'm saying, I'm not vehemently opposed to it and could do it, but it just seems like massive overkill and not at all necessary. Things are intentionally as simple and straightforward as can be. Jason
