While we're at this: According to the comments in the code, the purpose of the masterclock scheme is to prevent any vCPU from seeing an outdated hv_clock of another vCPU. However I'm missing how that is achieved. AFAICS the guest entry is allowed as soon as all vCPUs are kicked from guest with KVM_REQ_CLOCK_UPDATE set; what stops one vCPU from processing it and entering the guest before another vCPU even started updating its hv_clock?
