    The only reasonable explanation I can imagine for the weird stuff
    going on with "numa01_inverse" is that maybe it was compiled without
    -DHARD_BIND? I forgot to specify -DINVERSE_BIND is a noop unless
    -DHARD_BIND is specified too at the same time. -DINVERSE_BIND alone
    results in the default build without -D parameters.

    Now AutoNUMA has a bug and is real inverse bind too, I need to fix that.

    In the meantime this is possible:

    echo 0 >/sys/kernel/mm/autonuma/enabled
    run numa01_inverse
    echo 1 >/sys/kernel/mm/autonuma/enabled
