    That's why I put fatattrs in the system namespace, which is wholly owned
    by the Linux kernel. Any theoretical FAT-with-xattrs variant would put
    those xattrs in the user namespace.

    On another note, NTFS-style xattrs (aka named streams) are unrelated to
    Linux xattrs. A named stream is a separate file with a funny name, while
    a Linux xattr is a named extension to struct stat.
