This is not equivalent (unless there is a DEBUG macro definition hinding
in a header file somewhere). Since the changelog doesn't mention
suppressing any output, perhaps you were deceived by the questionable API,
as I have been in the past (see 16b9d870a0 and d61c5427f6).

This is an actual message people want to see in the kernel log, even
when not debugging?


That's really a question for Atari users, of course. For my part, I think 
you should mention the behavioural change in the commit log.
