[AMD Official Use Only - General] Issue: during evict or validate happened on amdgpu_bo, the 'from' and 'to' is always same in ftrace event of amdgpu_bo_move where calling the 'trace_amdgpu_bo_move', the comment says move_notify is called before move happens, but actually it is called after move happens, here the new_mem is same as bo->resource Fix: move trace_amdgpu_bo_move from move_notify to amdgpu_bo_move Signed-off-by: Wang, Beyond
