I've noticed that there is no interfaces exposed by CMA which would let me fuzz what's going on in there.
This small patch set exposes some information out to userspace, plus adds the ability to trigger allocation and freeing from userspace. Changes from v1: - Make allocation and free hooks per-cma. - Remove additional debug prints.
