Thanks! commit df0bb47baa95aad133820b149851d5b94cbc6790 Author: Paolo Bonzini <pbonzini@xxxxxxxxxx> Date: Wed Nov 30 11:14:35 2022 -0500 KVM: x86: fix uninitialized variable use on KVM_REQ_TRIPLE_FAULT If a triple fault was fixed by kvm_x86_ops.nested_ops->triple_fault (by turning it into a vmexit), there is no need to leave vcpu_enter_guest(). Any vcpu->requests will be caught later before the actual vmentry, and in fact vcpu_enter_guest() was not initializing the "r" variable. Depending on the compiler's whims, this could cause the x86_64/triple_fault_event_test test to fail.
