    Yes, you need a:

    echo 40 500 64 256 0 >/proc/sys/vm/bdflush

    to disable kupdate. Then it will go to sleep.

    To reenable kupdate you need to:

    echo 40 500 64 256 500 >/proc/sys/vm/bdflush

    and _then_ send it a SIGCONT. (note on Alpha the second 500 has to be
    close to 5000 since HZ is 1024 there)

    That was intentional to make sure nobody is going to STOP kupdate by
    mistake. If you think it's better to allow kupdate to be stopped simply
    via a SIGSTOP I can change the code.
