Subject: [PATCH v6 11/22] KVM: x86/mmu: Replace vcpu with kvm in kvm_mmu_alloc_shadow_page()
Date: Mon, 16 May 2022 23:21:27 +0000 [thread overview]
Message-ID: <20220516232138.1783324-12-dmatlack@google.com> (raw)
In-Reply-To: <20220516232138.1783324-1-dmatlack@google.com>
The vcpu pointer in kvm_mmu_alloc_shadow_page() is only used to get the
kvm pointer. So drop the vcpu pointer and just pass in the kvm pointer.
No functional change intended.
