While I'm still unable to help noticing things, nobody seems to have presented an argument that user-space and kernel-side will need to be developed together. There's been an obvious assumption, with oprofile given as that assumption's poster-boy, but why that should be the case for tools/perf remains unclear. Probably the reasons are so obvious that they go without saying, but as a disinterested observer, it seems to me that in this case the two sides really are quite separate and independent in a very real sense. Perhaps in the same sense that acct and quota are. -- 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/
