This is v12 of the server side changes to enable vfio-user in QEMU.

Thanks so much for reviewing this series and sharing your feedback.

We made the following changes in this series:
[PATCH v12 13/14] vfio-user: handle device interrupts
 - Renamed msi_set_irq_state() and msix_set_irq_state() as
   msi_set_mask() and msix_set_mask() respectively
 - Added missing return statement for error case in msi_set_mask()

Thank you very much!

You're welcome! Thanks for the persistence in getting the vfio-user
server into QEMU.

I have mirrored libvfio-user here:
https://gitlab.com/qemu-project/libvfio-user

The QEMU project's policy is to mirror dependencies so full source code
can be provided even in the event that dependencies become unavailable.
The mirror is currently manually updated, so please ping me if you want
newer commits.

Thanks,
Stefan

I have semi-automated the mirroring. As long as I use my laptop the
repo will be kept up-to-date. :)
