Does not apply for me.  What's your base?

The base I used is f5643914a9e8f79c606a76e6a9d7ea82a3fc3e65.

The patchew tool says it was able to apply the patches:
https://patchew.org/QEMU/cover.1651586203.git.jag.raman@oracle.com/

The client side changes required are still under review. But the
following repo has this series applied on top of the client:
repo URL: https://github.com/oracle/qemu
branch: vfio-user-v5client-v9server

Thank you!

Local tooling error, sorry for the noise.
