Yifan Liu ffc142d9be hv: sched_event: Change nqueued from int8_t to int32_t ... This patch changes the type of nqueued in struct sched_event from int8_t to int32_t. In commit d575edf79, the 1 bit flag in struct sched_event has been changed to int8_t counter to resolve race condition. Signal_event will decrease the counter and wait_event will increase it and loop if the counter is greater than 0. In most cases the uses of signal_event and wait_event are consistent, except VCPU_EVENT_VIRTUAL_INTERRUPT. In our logic, we signal this event whenever there is an virtual interrupt, but we wait on it only in hlt_vmexit_handler, and we reset this event before VMEnter. In most cases this worked fine. However it has been found that in certain GPU stress testing scenario, the signaling of this event happened too frequently to the point where this int8_t counter underflowed (i.e., hit -128 and then became 127). Then in subsequent hlt_vmexit_handler, hv waited on this event and stuck there as the counter was too large. This patch changes the type from int8_t to int32_t to avoid underflow.
