When it comes to trace events, there's a fine line about the use space stable ABI. Even Linus has mentioned that tracing and perf counters are "special", as the two are not about a feature of the kernel, but instead a way to see how the kernel works internally. I've fixed up trace-cmd and libtraceevent more than once in the past due to changes in the kernel. Unless it truly breaks the tool, it should be fine to fix up tracepoints to handle small changes like this. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
