  35           to set up connections and directly access InfiniBand
  36           hardware for fast-path operations.  You will also need

  54           On demand paging support for the InfiniBand subsystem.
  55           Together with driver support this allows registration of
  56           memory regions without pinning their pages, fetching the
  57           pages on demand instead.
