+  * 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
