Subject: [PATCH 03/11] vfio-pci: rename vfio_pci_device to vfio_pci_core_device
Date: Thu, 3 Jun 2021 19:08:01 +0300 [thread overview]
Message-ID: <20210603160809.15845-4-mgurtovoy@nvidia.com> (raw)
In-Reply-To: <20210603160809.15845-1-mgurtovoy@nvidia.com>
This is a preparation patch for separating the vfio_pci driver to a
subsystem driver and a generic pci driver. This patch doesn't change
any logic. The new vfio_pci_core_device structure will be the main
structure of the core driver and later on vfio_pci_device structure will
be the main structure of the generic vfio_pci driver.
