[PATCH 2/3] Change perturb_period to unsigned.

[Corey Hickey <bugfood-ml@fatooh.org>]

This corresponds to the kernel patch doing the same.

Here, too, this will technically break binary compatibility with older
kernels, but that shouldn't be a problem because negative perturb_period
values aren't usable anyway.
