If the limit depends on what is measured, what should be the reasonable default value? I just don't know.. I agree that we should pick a default but the config variable doesn't harm anything in this case too. Some users might not agree with our default for their cases and want to use other value. But I'm not insist on it so strongly, I just gave another way.. ;) Thanks, Namhyung -- 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/
