You and Karim may be in violent agreement, even if others haven't quite come around: Let us design a static marker mechanism that can be coupled at run time either to a dynamic system such as systemtap, or by a specialized tracing system such as lttnng (!). Then "markers" === "static instrumentation", for purposes of the kernel developer. If the markers are lightweight enough, then a distribution kernel can afford keeping them compiled in. - FChE - 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/
