	 * This function should be called by any #GVolumeMonitor
	 * implementation when a new #GMount object is created that is not
	 * associated with a #GVolume object. It must be called just before
	 * emitting the @mount_added signal.
	 *
	 * If the return value is not %NULL, the caller must associate the
	 * returned #GVolume object with the #GMount. This involves returning
	 * it in its g_mount_get_volume() implementation. The caller must
	 * also listen for the "removed" signal on the returned object
	 * and give up its reference when handling that signal
	 *
	 * Similary, if implementing g_volume_monitor_adopt_orphan_mount(),
	 * the implementor must take a reference to @mount and return it in
	 * its g_volume_get_mount() implemented. Also, the implementor must
	 * listen for the "unmounted" signal on @mount and give up its
	 * reference upon handling that signal.
	 *
	 * There are two main use cases for this function.
	 *
	 * One is when implementing a user space file system driver that reads
	 * blocks of a block device that is already represented by the native
	 * volume monitor (for example a CD Audio file system driver). Such
	 * a driver will generate its own #GMount object that needs to be
	 * associated with the #GVolume object that represents the volume.
	 *
	 * The other is for implementing a #GVolumeMonitor whose sole purpose
	 * is to return #GVolume objects representing entries in the users
	 * "favorite servers" list or similar.
	 *
	 * Deprecated: Instead of using this function, #GVolumeMonitor
	 * implementations should instead create shadow mounts with the URI of
	 * the mount they intend to adopt. See the proxy volume monitor in
	 * gvfs for an example of this. Also see g_mount_is_shadowed(),
	 * g_mount_shadow() and g_mount_unshadow() functions.
	 *
	 * Params:
	 *     mount = a #GMount object to find a parent for
	 *
	 * Returns: the #GVolume object that is the parent for @mount or %NULL
	 *     if no wants to adopt the #GMount.
