SubjectRE: [PATCH v3 3/3] Drivers: hv: vmbus: Add module parameter to cap the VMBus version
Date
From: Andrea Parri <parri.andrea@gmail.com> Sent: Tuesday, October 15, 2019 4:47 AM

> Currently, Linux guests negotiate the VMBus version with Hyper-V
> and use the highest available VMBus version they can connect to.
> This has some drawbacks: by using the highest available version,
> certain code paths are never executed and can not be tested when
> the guest runs on the newest host.
>
> Add the module parameter "max_version", to upper-bound the VMBus
> versions guests can negotiate.
