    Hi, all:

    I've been reading sched_ule.c and seem to find a serious error:

    in 'sched_slice()':

             * Rationale:
             * KSEs in interactive ksegs get the minimum slice so that we
             * quickly notice if it abuses its advantage.

    Then, there is:

            if (!SCHED_INTERACTIVE(kg)) {
                    .....
                    .....
            } else
                    ke->ke_slice = SCHED_SLICE_INTERACTIVE;

    Then, at the beginning of the file, there is:

    #define SCHED_SLICE_INTERACTIVE (slice_max)

    (slice_max) for interactive KSEs???? Either this is a serious mistake or
    I'm seriously missing sth here.

    Thanks,
    Bin
