Whenever I try to make variables or function names more explicit, I can
literally feel my consciousness (taking the form of an angry Peter Zijlstra)
breathing down my neck asking me to make them shorter. So I guess this is
where it becomes a question of taste.

I think the "rseq" syscall name is short, to the point, and should be mostly
fine.

For "cpu_opv", it was just a short name that fit the bill until a
better idea would come.

I'm open to suggestions. Any color preference ? ;-)

Thanks,

Mathieu
