Hi, The PCI p2p and tunnel code is used by the Mellanox CX5 driver, at least their latest, out of tree version, which is used for CORAL. My understanding is that they'll upstream it at some point, though I don't know what their schedule is like.
As said before, we only keep exports in tree for in-tree users. If the CX5 driver grows special P2P support it will have to use the proper existing kernel infrastructure for that anyway.
