I tried to apply this commit to the linux and linux-next repositories 
and run tests.

However, I’m unable to apply [PATCH 19/21] vfio: selftests: Expose 
low-level helper routines for setting up struct vfio_pci_device, because 
the related source code has changed significantly in both linux and 
linux-next.

If you plan to resend this patch series based on the latest linux or 
linux-next, please feel free to ignore this comment.

I look forward to testing the updated patch series once it is available.

Best Regards,

Yanjun.Zhu
