Subject: [PATCH v4 08/21] KVM: selftests: Add a "struct kvm_mmu_arch arch" member to kvm_mmu
Date: Tue, 30 Dec 2025 15:01:37 -0800 [thread overview]
Message-ID: <20251230230150.4150236-9-seanjc@google.com> (raw)
In-Reply-To: <20251230230150.4150236-1-seanjc@google.com>
Add an arch structure+field in "struct kvm_mmu" so that architectures can
track arch-specific information for a given MMU.
No functional change intended.
