But this seems to be a temporary code, as it will be removed in patch 09/25.It looked OK when I checked it, mkt_v1 is really confusing what it tries to do, but it should call probe_finalize and basically do the same hacky thing as what UNMANAGED was trying to accomplish. Did you see something else?
