I wasn't sure exactly what you intended with the request to "update before
Assuming the statistics update is done as part of radeon_bo_move_notify(), I
believe that function cannot be called any earlier in radeon_bo_move(). If it
were, the source object would be invalidated before it moved.
So I assume you're suggesting updating the memory usage earlier in
bo_move_notify (before the early return for ghost objects).
