| * Since cifs is a network file system, an "fsid" must be included for | |
| * any nfs exports file entries which refer to cifs paths. In addition | |
| * the cifs mount must be mounted with the "serverino" option (ie use stable | |
| * server inode numbers instead of locally generated temporary ones). | |
| * Although cifs inodes do not use generation numbers (have generation number | |
| * of zero) - the inode number alone should be good enough for simple cases | |
| * in which users want to export cifs shares with NFS. The decode and encode | |
| * could be improved by using a new routine which expects 64 bit inode numbers | |
| * instead of the default 32 bit routines in fs/exportfs | |
