sys_sysfs doesn't have anything to do with /sys/ and udev in any way that I know of, it's a much older thing, a sysv syscall that can return the index, name, or max index of a filesystem. And yes, I got confused by it all the time when creating sysfs :) thanks, greg k-h -- 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/
