The "version number" is the size of the struct. Any extensions we make
are appended to the struct (openat2 now takes a size_t argument), and
the new copy_struct_{to,from}_user() helpers handle all of the
permutations of {old,new} kernel and {old,new} user space.
This is how clone3(), sched_[gs]etattr() and perf_event_open() all
operate (all of the sigset syscalls operate similarly but don't
gracefully handle different kernel vintages -- you just get -EINVAL).
