Arghh... you don't _want_ to understand, right?
I was referring to my reply to your cover letter (patch 0/8) within
this very patch series. It makes little sense to repeat what I've
already told you just one or two messages before, or does it?

Yes, I do mean __log_buf resp. the syslog services.
Yes, this will end up in the log buffer than can be displayed with
dmesg.
If you consider this information "crud", then consider to disable the
feature.
But then, guess why highres timestamps have been added to the kenrel
logs? For people not interested in such informtion this is eventually
"crud", but for others it appears important enough that it got added
to Linux mainline.
If you are not interested in such information, then just use
appropriate log levels and filtering.

Guess how many tools are out there that already deal with filtering
and post-processing of kernel log messages? A google search for
"syslog filter" returns millions of hits...
