It is not about whether it is important or not - the question is whether
changing existing functionality which someone might rely upon is a
problem here? Someone might be expecting exactly those messages to
appear in dmesg.
If so, how will disabling dmesg output and switching to a trace event
help? The user-space program will still break unless they add support
for that trace event, right?
I'm not sure if we actually provide guarantees w.r.t kernel log
messages. The issue in this specific scenario is the sheer verbosity of
the log messages. I personally feel that it will be good if we can
simplify the log output.
Thanks,
