Sounds funny.  Maybe better with just:

Returns: the list of names

Also, is list of names sufficient, or are we better off returning a list
of structs with the details already included?  With list of names, the
management app has to follow up with another QMP command per name if it
wants to know details about each node, instead of getting it all in one
command.

Return a list of strings containing the name of each named block driver node
