Hmm.  I didn't think anyone was looking at this data besides myself.
The site is really still under construction, so I apologize for missing
and mis-formatted data.  But thanks for looking at
the data and finding something that needs attention upstream!!

Wow, that's interesting.  Here's the lore link for this thread:
https://lore.kernel.org/lkml/[email protected]/#t

It doesn't look like there were (after discussion) objections to accepting upstream.
I wonder what happened.

...
It looks like it was superceded by this patch:
https://lore.kernel.org/lkml/[email protected]/
which may provide some of the data necessary.

The thing missing there are some (IMHO) better name lookups for the probe function.
I wrote a patch for that, but didn't persist in trying to upstream it.  Maybe I should
dust that off and send it again.
