Subject: [RFC PATCH v2 1/9] vfio/pci: split vfio_pci_device into public and
 private parts
Date: Thu, 30 Jan 2020 21:09:56 -0500
Message-Id: <20200131020956.27604-1-yan.y.zhao@intel.com>
X-Mailer: git-send-email 2.17.1
In-Reply-To: <20200131020803.27519-1-yan.y.zhao@intel.com>
References: <20200131020803.27519-1-yan.y.zhao@intel.com>
Sender: kvm-owner@vger.kernel.org
Precedence: bulk
List-ID: <kvm.vger.kernel.org>
X-Mailing-List: kvm@vger.kernel.org

split vfio_pci_device into two parts:
(1) a public part,
    including pdev, num_region, irq_type which are accessible from
    outside of vfio.
(2) a private part,
    a pointer to vfio_pci_device_private, only accessible within vfio
