My concern is the (large) performance regression with specjbb and volanomark, due to increased idle time. We cannot just jam all this code into Linus's tree while crossing our fingers and hoping that something will turn up to fix this problem. Because we don't know what causes it, nor whether we even _can_ fix it. So this is the problem which everyone who is working on the CPU scheduler should be concentrating on, please. - 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/
