Subject: [PATCH v3 03/36] KVM: arm64: Rename __pkvm_pgtable_stage2_unmap()
Date: Thu, 5 Mar 2026 14:43:16 +0000 [thread overview]
Message-ID: <20260305144351.17071-4-will@kernel.org> (raw)
In-Reply-To: <20260305144351.17071-1-will@kernel.org>
In preparation for adding support for protected VMs, where pages are
donated rather than shared, rename __pkvm_pgtable_stage2_unmap() to
__pkvm_pgtable_stage2_unshare() to make it clearer about what is going
on.
