This is a tricky one.
But first, why aren't those tests failing similarly with the original
patch?
Also, If we were to use system dma-buf with the exported bo WB, then
the app would fail anyway?
Perhaps we should use a separate test for p2p dma-bufs (attach-
>peer2peer), but then again UMD wouldn't know whether it's peer2peer or
not.
I think if we need to access cross-device bos for metadata, we need to
check with Sima / Dave first. I don't think that's something that is
encouraged, really.
