[PATCH v3] virtio-balloon: Switch back to OOM handler for VIRTIO_BALLOON_F_DEFLATE_ON_OOM
Commit 71994620bb25 ("virtio_balloon: replace oom notifier with shrinker")
changed the behavior when deflation happens automatically. Instead of
deflating when called by the OOM handler, the shrinker is used.
However, the balloon is not simply some other slab cache that should be
shrunk when under memory pressure. The shrinker does not have a concept of
priorities yet, so this behavior
