In general, IMO, I agree with Roland at https://lkml.org/lkml/2002/12/20/84 in that it's good to have setters for completeness, so that you can change all the state via ptrace that you can read via ptrace. But I'm not doing any of this work, hence my "could always be added later" comment instead of actually requesting it. But if we had it, we could make e.g., gdb inspect the signal queues, and then be able to tweak a realtime signal before it is delivered. -- Pedro Alves -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
