This looks like a change in the semantics of the tracepoint. Before this
change, 'waited' would have been true if the vcpu waited at all. Here, you'd
have false if it has been interrupted by a signal, even if the vcpu has waited
for a period of time.

Hmm but sleeps are now uninterruptible as we're using TASK_IDLE.

Thanks,
