Subject: [PATCH] kvm: delete unused variables iommu_noncoherent in struct kvm_arch
Date: Thu, 6 Feb 2025 10:26:56 +0800 [thread overview]
Message-ID: <20250206022656.3752383-1-fuqiang.wng@gmail.com> (raw)
The code of legacy device assignment is deleted entirely in commit
ad6260da1e23 ("KVM: x86: drop legacy device assignment") and the
variable iommu_noncoherent in struct kvm_arch is also not referenced by
any other code. So it is deleted in this patch.
