Subject: [RFC PATCH 27/42] KVM: x86/mmu: change param "vcpu" to "kvm" in kvm_mmu_hugepage_adjust()
Date: Sat,  2 Dec 2023 17:28:50 +0800	[thread overview]
Message-ID: <20231202092850.15107-1-yan.y.zhao@intel.com> (raw)
In-Reply-To: <20231202091211.13376-1-yan.y.zhao@intel.com>

kvm_mmu_hugepage_adjust() requires "vcpu" only to get "vcpu->kvm".
Switch to pass in "kvm" directly.

No functional changes expected.
