This isn't the helper that needs to be exported, it's a include wrapper
that is using this for cgroups. Please document this much better and
perhaps, just fix up the cgroups code instead?
Thanks for the notice, I didn't think much of this, just export API that
is called from iocost. I'll look into this.
Thanks,
Kuai
