Sure, I'm doing the review/test now, but at the same time, stressing that you _can_ shortcut all that and, having a suitable .o file, use all the other perf features with it is also cool and something worth pointing out. To _have to_ produce a .o to use this is, of course, bad and shortly will be done completely automatically in as a streamlined way as we can conceive. - Arnaldo -- 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/
