That was suggested for your convenience only, feel free to keep it the
way you want it.

I forgot about the one-value-per-file thing really, but we are using
that for cpufreq-stats as well.

And now that you have mentioned that to me, why shouldn't this stats
directory be moved to debugfs ? :)

We are never going to perform a store here, isn't it ? And is just for
information, nothing more.
