Subject: [RFC PATCH 03/37] KVM: MMU: Move tdp_ptep_t into common code
Date: Thu, 8 Dec 2022 11:38:23 -0800 [thread overview]
Message-ID: <20221208193857.4090582-4-dmatlack@google.com> (raw)
In-Reply-To: <20221208193857.4090582-1-dmatlack@google.com>
Move the definition of tdp_ptep_t into kvm/mmu_types.h so it can be used
from common code in future commits.
No functional changed intended.
