We try using cancel_delayed_work_sync() to prevent the work from
enabling NAPI. This is insufficient since we don't disable the the

cancel_delayed_work_sync() can schedule the refill work then can
re-enable the NAPI that leads to

This patchset introduces memory shrinker for the VirtIO-GPU DRM driver

The new dma-buf locking convention is introduced here as well.
