But this is the last patch of the series, so I can only guess whether it might be okay to go in ahead of the other three patches. Jan I am wondering, where this patch could be 4.17 material? The patch series seem to get stuck, but the current patch just adds a missing include to fix a build on Arm, so it is completely independent. I agree, there is no issue with the current code base as vPCI is disabled on Arm, so nothing to fix right now. But as PCI passthrough/vPCI on Arm is in the development stage, the developers enable that support in their builds. I think the risk is rather low than high. -- Regards, Oleksandr Tyshchenko
