The only things this protects is reading ->flags and ->size, both of which are invariant over the lifetime of an exynos gem bo. So no locking needed at all (besides that, nothing protects the writers anyway). Aside: exynos_gem_obj->size is redundant with exynos_gem_obj->base.size and probably should be removed. v2: Use _unlocked unreference (Daniel Stone).
