Cheers to you too!

Pulled, I'll try to get it out for Linus to include it in -rc2 still.

Just a quick comment, this one has
Fixes: 7e00897be8bf ("drm/i915: Add object locking to i915_gem_evict_for_node and i915_gem_evict_something, v2.")
but I don't think that's entirely accurate. I might mix up some details
(and today is not the day to dig these out) and it's been two years
already when I discussed this Maarten, but this issue is older. It got
introduced with the conversion to per-object locking, and then somewhat
artfully papered over with the async object pinning infrastructure (which
had the design issue of being flat out in violation of upstream locking
hierarchy).
In practice it makes no difference, because there's no way you can
backport any of this to a point before the locking rework from Maarten (or
alternatively, revert until the glorious struct_mutex days). A bit more
review on a core locking change like this would have been good though imo.
Cheers, Daniel
