Those are the only two gray areas... the safety margin is large enough that nobody notices the lack of black-and-white solution. So instead of working to provide guarantees for the above two gray spots, we're making everything weaker, that's the wrong direction as far as I can tell, especially if we're going to mess up big time the commo code in a backwards way only for those few users of those few I/O devices out there. In general every time reliability has a low priority than performance I've an hard time to enjoy it. - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
