From: Rob Clark <[email protected]> Previously we'd also tear down the VMA, making the address space available again. But with drm_gpuvm conversion, this would require holding the locks of all VMs the GEM object is mapped in. Which is problematic for the shrinker.
Instead just let the VMA hang around until the GEM object is freed.
