My understanding is that
1) There will be only one hypercall at any point of time( there is no queue). Is this right?
2) This hypercall can poll for events/work to do in case it is preemptable. Is there any way that the hypercall can be made non-preemptable?
Thanks,
Sowmya.

Preemption is voluntary. Long-lived hypercalls poll for pending events
/ work to do.
