There is one example whethere dynamic tracing is difficult or very messy to implement and that's for tracepoints needed during system and device initialization. In this sense dynamic is not a practical superset of static. However I believe the tooling, for dynamic trace should work for static as well. - - Richard J Moore IBM Advanced Linux Response Team - Linux Technology Centre MOBEX: 264807; Mobile (+44) (0)7739-875237 Office: (+44) (0)1962-817072 - 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/
