From 7cdcdfe50d8d68b7b9ba2e1b0345ff47fdda390f Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Wed, 16 Feb 2022 12:40:18 -0800 Subject: [PATCH] KVM: selftests: Convert s390x/diag318_test_handler away from VCPU_ID Convert diag318_test_handler to use vm_create_with_vcpus() and pass around a 'struct kvm_vcpu' object instead of passing around vCPU IDs. Note, this is a "functional" change in the sense that the test now creates a vCPU with vcpu_id==0 instead of vcpu_id==6. The non-zero VCPU_ID was 100% arbitrary and added little to no validation coverage. If testing non-zero vCPU IDs is desirable for generic tests, that can be done in the future by tweaking the VM creation helpers.
