-Subject: [PATCH 0430/1110] drm/amdgpu: fence wait old rcu slot
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-since the rcu slot was initialized to be num_hw_submission,
-if command submission doesn't use scheduler, this limitation
-will be invalid like uvd test.
