    Unmounts ZFS file systems

    name : string
        name of the filesystem, you can use None to unmount all mounted filesystems.
    force : boolean
        forcefully unmount the file system, even if it is currently in use.

    .. warning::

        Using ``-a`` for the name parameter will probably break your system, unless your rootfs is not on zfs.

    .. versionadded:: 2016.3.0
    .. versionchanged:: 2018.3.1

    .. warning::

            Passing '-a' as name is deprecated and will be removed in Sodium.

    CLI Example:

    .. code-block:: bash

        salt '*' zfs.unmount myzpool/mydataset [force=True|False]
