    [$] Controlling device peer-to-peer access from user space
    The recent addition of
    support for direct (peer-to-peer) operations between PCIe devices     in the
    kernel has opened the door for different use cases. The initial work
    concentrated on in-kernel support and the NVMe subsystem; it also
    added support for memory regions that can be used for such transfers.
    Jérôme Glisse recently proposed
    two extensions     that would allow the mapping of those regions into user
    space and mapping device files between two devices.
    The resulting discussion surprisingly led to consideration of the
    future of core kernel structures dealing with memory management.
