[PATCH 02/11] uml ubd driver: document some struct fields

["Paolo 'Blaisorblade' Giarrusso" <blaisorblade@yahoo.it>]

From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

Add documentation about some fields in struct ubd, whose meaning is non-obvious
due to struct names (should change names altogether, I agree).

Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>
