Subject: [PATCH v6 14/22] KVM: x86/mmu: Pass const memslot to rmap_add()
Date: Mon, 16 May 2022 23:21:30 +0000 [thread overview]
Message-ID: <20220516232138.1783324-15-dmatlack@google.com> (raw)
In-Reply-To: <20220516232138.1783324-1-dmatlack@google.com>
rmap_add() only uses the slot to call gfn_to_rmap() which takes a const
memslot.
No functional change intended.
