It's that I don't like out-of-line documentation. It's a damn pain to
maintain, and it's _especially_ so when it's for small details rather than
"big picture" issues.

I also consider this to be _exactly_ the same issue as translating kernel
messages into another language (which people have also wanted to do),
except the "other language" is a S390-specific "odd-speak" rather than a
real language.

I have to say that I also dislike the technical implementation. I don't
like having yet another printk() wrapper - your "kmsg_warn()" won't play
well with people who have messages they want to print, but that use helper
routines - or then you'd need to essentially change _every_ printk to a

So if you want to have a hash (so that you can identify the _format_
string rather than the printed out message), I personally think you'd be
better off thinking of it purely the same way as CONFIG_PRINTK_TIME, and
just have a config option that disables or enables the hashing of the
format string, the same way we have an option for disabling or enabling of
the timestamping of the printk.

I also suspect that it would be better to not _print_ it, but only put it
into the dmesg logs (the same way we do with the urgency level marker).

IOW, I think we could put a few lines of code in "vprintk" that just
hashes ove 'fmt' and then adds that to the output.

And as for the actual explanations: either they need to be totally outside
the kernel (in a project of their own), or they'd need to be "kernel-doc"
style things that are _in_ the source code. Not in Documentation/. Not
separate from the printk() that they are associated with.
