Subject: [PATCH v18 11/23] KVM: arm64: Use kvm_vm_is_unprotected() for !kvm_vm_is_protected()
Date: Tue, 15 Sep 2026 17:01:29 +0100 [thread overview]
Message-ID: <20260915160141.3543048-12-suzuki.poulose@arm.com> (raw)
In-Reply-To: <20260915160141.3543048-1-suzuki.poulose@arm.com>
Now that we have a flavor to check, use the helper to explicitly check
the type for an unprotected PKVM guest. We don't convert all of the
!kvm_vm_is_protected(), but only the ones that target unprotected PKVM
guests.
