    This sounds reasonable. The people who shipped that already to
    customers have so heavily patched kernels, that this simple patch
    for the old sys_futex shouldn't really matter.

    But cluttering the kernel with an API/ABI that was born in the
    same development cycle, where it has been obsoleted sounds not
    worth the bytes it consumes. And so we have a syscall slot
    available for the next development cycle.

    Or did anybody promise that this was final already? Usally this
    promise comes with x.even.y not with x.odd.y .
