+Subject: [PATCH 0224/1050] drm/amdgpu: drop AMDGPU_FENCE_SIGNALED_SEQ
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It's causing issues with VMID handling and comparing the
+fence value two times actually doesn't make handling faster.
+
+Port of radeon commit "d6d5c5b8364bcc4d52cddc68bcb0a330d2af20f3".
