VMClock now supports a vm_generation_counter field in the struct it
exposes to userspace. The field signals a disruption that happened due

Moreover, VMClock now optionally supports device notifications when the

Please either do a full linux-headers update against a specific Linux
kernel version, or mark this as a placeholder patch if the code is not
yet merged.

Indeed, that's a placeholder. What's the process to mark this as a placeholder?

Cheers,
Babis
