That's a good question, and afaict it remains unanswered.

As so often happens, this patchset's changelogs forgot to describe the
reason for the existence of this patchset.  Via a bit of lwn reading
and my awesome telepathic skills, I divine that something in networking
is using syslog for kernel->userspace communications.

wtf?

Wouldn't it be better to just stop doing that, and to implement a
respectable and reliable kernel->userspace messaging scheme?

And leave syslog alone - it's a crude low-level thing for random
unexpected things which operators might want to know about.
