commit 08ac42b8c6892a9c8447ceefd931bc4394bef8fb (HEAD, upstream/master) Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Jan 16 13:08:11 2019 +0000 drm/drm_import_export: Replace imprecise loop-bound with timeout Use a specific timeout to exercise the race conditions, rather than a number of tries -- this prevents it burning up too many minutes under CI for little gain, we can just run it again to improve race detection.
