Maybe we can do below in handle_bus_lock_vmexit handler:
if (!to_vmx(vcpu)->exit_reason.bus_lock_detected)
to_vmx(vcpu)->exit_reason.bus_lock_detected = 1;
But is manually changing the hardware reported value for software
purpose a good thing?
No. That said, Hao's patch is just making the code clearer; there's no
behavioral change since the "if" will just redo the same assignments as
handle_bus_lock_vmexit.
