Well, the disagreement in definition of "being used". Quite often you have a device "open" for extended period of time (inactive ext2 partition is mounted on a disk) but device is not really active. You could power it down and only wake up when there is a read or write request. It looks like "open" and "close" are terms better suited for class devices while power management is applied to the "real" devices. -- Dmitry - 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/
