If there were no way around implementing kprobes, I would completely agree with you. Let's take an item from todo list: TLS support for m68k. This a language feature becoming more and more important and increasingly difficult to work around it. Considering the complexities of this feature it will take quite a bit of the time available to me and somehow I doubt someone will beat me to it. I'm not complaining about it, I even enjoy hacking on it, but I also have to take no shit on how I have to spend my time. Considering this I hope you understand how important kprobes are to me, I admit it's a nice a feature, but it's far from being essential. bye, Roman - 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/
