Subject: [PATCH 1/6] KVM: Documentation: Add the missing guest_mode in kvm_mmu_page_role
Date: Sun, 18 Jun 2023 00:08:51 +0000 [thread overview]
Message-ID: <20230618000856.1714902-2-mizhang@google.com> (raw)
In-Reply-To: <20230618000856.1714902-1-mizhang@google.com>
Add the missing guest_mode in kvm_mmu_page_role description. guest_mode
tells KVM whether a shadow page is used for the L1 or an L2. Update the
missing field in documentation.
