From 6f96628f8290d2b634ba0dc5b83bd7201e099c52 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Tue, 15 Feb 2022 16:23:43 -0800 Subject: [PATCH] KVM: selftests: Convert vmx_nested_tsc_scaling_test away from VCPU_ID Convert vmx_nested_tsc_scaling_test to use vm_create_with_one_vcpu() and pass around a 'struct kvm_vcpu' object instead of using a global VCPU_ID.
