I've done a quick check by parsing the older cifs_parse_mount_options
to print out the list of mount options supported and compared this
output to the list of mount options supported by the current parser and
it appears that following the forcegid/noforcegid option, we have
accounted for all the other mount options.

There have been a number of mount options which have changed since.
example: cache, vers. These have been accounted for.
