I don't think it makes a big difference whether we change it now or later,
but if Christoph feels that it addresses his concern about the compat_
namespace being reused during the transition, doing it earlier would
enable us to finish the remaining syscalls.

We are running a little late with the remaining syscalls for 4.19 as we
now have an rc5. At this point we probably won't have time to finish
the discussion about all of clock_adjtime, getrusage/waitid and getitimer(),
but I'd really like to get utimensat, futex, sched_rr_get_interval,
recvmmsg, sys_io_getevents, rt_sigtimedwait, ppoll and pselect6
done for 4.19 so we can finalize the ABI for 4.20 along with doing
the actual conversion.
