From 4b8de8e68a2a5e2e7bdd755eacf18b5e9ce1c729 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 4 Aug 2016 07:52:42 +0100 Subject: [PATCH] drm/i915: Move request list retirement to i915_gem_request.c As the list retirement is now clean of implementation details, we can move it closer to the request management.
