Subject: [PATCH v2 048/144] KVM: selftests: Rename 'struct vcpu' to 'struct kvm_vcpu'
From:   Sean Christopherson <seanjc@google.com>
To:     Paolo Bonzini <pbonzini@redhat.com>
Cc:     kvm@vger.kernel.org, Vitaly Kuznetsov <vkuznets@redhat.com>,
        Andrew Jones <drjones@redhat.com>,
        David Matlack <dmatlack@google.com>,

        Oliver Upton <oupton@google.com>, linux-kernel@vger.kernel.org
Content-Type: text/plain; charset="UTF-8"
Precedence: bulk

Rename 'struct vcpu' to 'struct kvm_vcpu' to align with 'struct kvm_vm'
in the selftest, and to give readers a hint that the struct is specific
to KVM.
