This is not what I wrote. Please check the process documentation, which
I already referenced in my comment in your v9 submission. Apart from
that my comment also applies to the other patch in this series.

You multiply these with 1000 (10 for temp) before returning them to
userspace. So you return (-ENODATA * 1000), which is obviously
wrong...
