/*
* See Documentation/filesystems/nfs/Exporting
* and examples in fs/exportfs
*
* 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
*
