Forgot to answer about that: That means that the current design does not cover our requirement of showing process real time, even if we implement sched_clock?

Of course better solutions are welcome :-) Christian - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
