Even filesystems that had UUIDs since the dawn of days don't always store it there, e.g. XFS. I wish people had left it with that, but the recent rush to stupidly overload it with an uuid light and using it in nfs-tools didn't help. Having an API to expose a UUID to userspace would be useful, but f_fsid isn't it. If we'll have to add real statvfs syscalls we can add an f_uuid field, but I'd rather not use up the reamining space in the statfs structure for that. -- 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
