BTW, when I took over from Vojtech, I looked at the suspend methods for the printer and it seemed possible that they can only work if the device is not open when suspend occurs. I was going to look at that at the first opportunity. So, I'd rather keep at least some kind of capability to suspend printers, even if disabled by default. I thought Matthew's patch was too harsh. -- Pete - 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/
