There are 3 remaining files without an extension inside the fs docs dir. Manually convert them to ReST. In the case of the nfs/exporting.rst file, as the nfs docs aren't ported yet, I opted to convert and add a :orphan: there, with should be removed when it gets added into a nfs-specific part of the fs documentation.

* 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
