Subject: [PATCH v3 0/2] Remove vfio_device_get_from_dev()
Date: Wed,  4 May 2022 16:01:46 -0300	[thread overview]
Message-ID: <0-v3-4adf6c1b8e7c+170-vfio_get_from_dev_jgg@nvidia.com> (raw)

Use drvdata instead of searching to find the struct vfio_device for the
pci_driver callbacks.

This applies on top of the gvt series and at least rc3 - there are no
conflicts with the mdev vfio_group series, or the iommu series.

v2:
 - Directly access the drvdata from vfio_pci_core by making drvdata always
   point to the core struct. This will help later patches adding PM
   callbacks as well.

  vfio/pci: Have all VFIO PCI drivers store the vfio_pci_core_device in
    drvdata
  vfio/pci: Remove vfio_device_get_from_dev()
