Which goes back to my earlier > arguments ... What do you want to prove with this rant ? Simply the fact that your view of tracing is not matching the view of others. Nothing else. You just made it clear, that your solution was and still is targeted on one single user group. Nobody is opposing instrumentation per se, we just need to figure out a good solution suitable for endusers, kernel developers, debug fetishists ... without splattering ten different tracers all across the kernel source. The way to a solid kernel instrumentation is definitely not by pushing a single purpose solution in, which we have to _maintain_ for a long time without being convinced that it is the _best_ technical solution we can have right now. tglx - 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/
