[Intel-gfx] [PATCH v4] drm/i915: Synchronize active and retire callbacks

[Sultan Alsawaf]

Chris,

Could you please look at this in earnest? This is a real bug that crashes my
laptop without any kind of provocation. It is undeniably a bug in i915, and I've
clearly described it in my patch. If you dont like the patch, I'm open to any
suggestions you have for an alternative solution. My goal here is to make i915
better, but it's difficult when communication only goes one way.

Thanks,
Sultan
