Heh, I understand. I do not see anything simple to implement... I'll try to think. Srikar, do you have any idea? All I can say right now: I'll send you the patches when I have them ;) Can't promise this will be soon. _Perhaps_, as a first step, we can simply change create_trace_uprobe() so that it would be possible to specify list-of-pids at creation time... Not sure this actually makes sense.
