SuS of course has to restrict itself, there are not that many flags which are portable and available on all the platforms. Look at /usr/include/bits/statvfs.h for what has to be supported and the values to use. If the values the kernel will use differ I'd have to (unnecessarily) convert the values. If some values are missing/not supported I still would have to use /proc/mounts and nothing is gained. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
