From 5a833995364141a3306e234500800277aea52334 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 2 Jun 2020 23:09:53 +0100 Subject: drm/i915: Drop i915_request.i915 backpointer We infrequently use the direct i915 backpointer from the i915_request, so do we really need to waste the space in the struct for it? 8 bytes from the most frequently allocated struct vs an 3 bytes and pointer chasing in using rq->engine->i915?
