[PATCH 0/1] MR146: vkd3d: Append a full memory barrier after the command list batch in ExecuteCommandLists().

[Conor McCarthy (＠cmccarthy)]

The D3D12 spec guarantees that lists submitted in ExecuteCommandLists()
will complete execution before any subsequent commands begin execution.

Based on a vkd3d-proton patch by Hans-Kristian Arntzen.
