Hmm one issue i didn't notice before: with imprecise backtrace the profiling could be a little random because even if the same call chain is hit repeatedly the garbage left over stack entries also reported could vary and then cause oprofile to put it into different buckets. But there is probably not much that can be done about that. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
