Also you may want to add something similar to this:

--- a/drivers/mtd/ubi/ubi.h
+++ b/drivers/mtd/ubi/ubi.h
@@ -339,7 +339,7 @@ struct ubi_volume {
 /**
  * struct ubi_volume_desc - UBI volume descriptor returned when it is opened.
  * @vol: reference to the corresponding volume description object
- * @mode: open mode (%UBI_READONLY, %UBI_READWRITE, or %UBI_EXCLUSIVE)
+ * @mode: open mode (%UBI_READONLY, %UBI_READWRITE, %UBI_EXCLUSIVE or
%UBI_METAONLY)
  */
 struct ubi_volume_desc {
        struct ubi_volume *vol;

There is also a similar mention in gluebi.c: 'readers/writes/exclusive'.

Thanks,
