We are looking at all the other pieces of SystemTap that can be merged to mainline but as Alan mentioned it is not easy and obvious. We think we can merge transport part of the runtime, here is the initial patch under review in this thread http://sources.redhat.com/ml/systemtap/2006-q4/msg00031.html http://sources.redhat.com/ml/systemtap/2006-q4/msg00030.html We are open for other suggestions as well. bye, Vara Prasad >Alan >- >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/ > > > - 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/
