I'm curious how you tested this series. Would it be posisble to write a selftest to exercise KVM's shrinker interactions? I don't think it needs to be anything fancy to be useful (e.g. just run a VM, trigger lots of shrinking, and make sure nothing blows up). There appears to be a debugfs interface which could be used to trigger shrinking from a selftest. https://docs.kernel.org/admin-guide/mm/shrinker_debugfs.html
