Exactly what use-case do you have in mind for this attribute?

"failed" is a strong word.
Some validation guy is going to send me e-mail when it is non-zero...
I don't like that use-case.

But even if re-named, I don't see see how it will be useful.
When I want to see how C-state predictions are doing, I use ftrace,
which can show me the actual expected and actual times, not just a count
of how man times predicted was < actual.
I would rather see some good tracepoints go upstream.

thanks,
