Subject: [RFC PATCH 0/3] Enforce DRM scheduler reclaim rules

Over the past year, I've randomly reviewed new drivers using the DRM
scheduler and repeatedly spotted misuses related to reclaim. This update
to the DRM scheduler aims to catch some of these misuses.

It's quite possible that this change will expose bugs in upstream
drivers, which is why it's being submitted as an RFC."
