This is revived patchset improving ref_tracker library and converting i915 internal tracker to ref_tracker. The old thread ended without consensus about small kernel allocations, which are performed under spinlock. I have tried to solve the problem by splitting the calls, but it results in complicated API, so I went back to original solution. If there are better solutions I am glad to discuss them. Meanwhile I send original patchset with addressed remaining comments.
