Has this been tested with popular userspace that reads /dev/kmsg, to make
sure that it actually plays nice with a 5th field being added?  Yes, I know
that Documentation/ABI/dev-kmsg says that added fields should be gracefully
ignored - but we all know how good userspace programmers are about that
sort of thing. :)
