This seems fine. Out of curiosity, when was the bad behavior this encountered?
During integration testing of the pmsg interface, we found that if any
(most notably ftrace) of the previous prz's were zero in length. Before
the addition of pmsg it would have occurred if you zero'd the console
size, but had ftrace set; an unlikely scenario _until_ pmsg was added.
