Re: [ClusterLabs] Antw: [EXT] Re: Q: high-priority messages from DLM?
Yeah I agree with you on all points, unless the author had a reason for those decisions 15 years ago. Most of us do our best to avoid touching DLM :) If anyone wants to make changes to the DLM logging macros, I'm in favor of it. I'm just not gonna lead the charge on it.

IMHO log_print is missing the priority/severity parameter... Comparing log_print(), log_error() and log_debug() I think that loggin code could benefit from some refactoring. Back on the subject: I think "Using SCTP for communications" is informational, not error, just as "closing connection to node 118" is probably notice, while "connecting to" / "connected to" is probably info or notice, too.
