From 4daffb664a69532efdfee54f3eac5ce54e8c37dd Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 21 Mar 2019 14:07:11 +0000 Subject: [PATCH] drm/i915: Stop storing the context name as the timeline name The timeline->name is only used for convenience in pretty printing the i915_request.fence->ops->get_timeline_name() and it is just as convenient to pull it from the gem_context directly. The few instances of its use inside GEM_TRACE() has proven more of a nuisance than helpful, so not worth saving imo.
