    To allow user unmounts of cifs shares (much like the setuid smbumount
    utility allows for smbfs), it has been suggested that the cifs vfs could
    return the uid of the mounter in /proc/mounts This would avoid having
    to add an ioctl (as smbfs did) and seems as secure as the ioctl approach
    (to get the uid of the original mounter).

    If user mounts are allowed, is there any worse security exposure in
    letting the tool check the uid who mounted via /proc/mounts (to allow
    user unmount).

    Is there any precedent for the name for the name of such a parm? I was
    thinking of "mnt_uid" since simply using "uid=" would seem to overload
    the meaning of "uid", which is already used as a mount parm by various
    filesystems to signify the default uid for files ( ie in the cifs case
    when mounting to Windows - and Unix CIFS protocol extensions are not
    enabled) and it is not always the case that the default uid for files
    would be the same as the uid of the person who mounted.
