Chris Wilson 50689771c8 drm/i915: Only close vma we open ... The history of i915_vma_close() is confusing, as is its use. As the lifetime of the i915_vma is currently bounded by the object it is attached to, we needed a means of identify when a vma was no longer in use by userspace (via the user's fd). This is further complicated by that only ppgtt vma should be closed at the user's behest, as the ggtt were always shared. Now that we attach the vma to a lut on the user's context, the open count does indicate how many unique and open context/vm are referencing this vma from the user. As such, we can and should just use the open_count to track when the vma is still in use by userspace. It's a poor man's replacement for reference counting.
