Store thread group leader id, and use it to lookup the address in the process's map. We could have looked up the address on thread's map, but the thread might not exist by the time we are called. The process might not exist either, but if you are reading trace_pipe, that is unlikely.

Honestly I'm not sure what this timeline stuff should mean. People are busy, and for many of us kernel hacking is only or at least outside of very narrow areas a spare time activicty, so you really can't expect answers in the next minute. There might be a lot of real life stuff that's a lot more important as it pais the bills and deals with family, etc. But that wasn't my point anyway. Al told no to seq_path, and just the contents of it without the interface that is tied to seq_files. Doing so is trivial by looking at seq_path so I really don't understand your odd reaction to it. -- 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/
