Subject: [PATCH 2/7] KVM: SVM: Use cached local variable in init_vmcb()
Date: Thu, 13 Mar 2025 21:55:35 +0000 [thread overview]
Message-ID: <20250313215540.4171762-3-yosry.ahmed@linux.dev> (raw)
In-Reply-To: <20250313215540.4171762-1-yosry.ahmed@linux.dev>
svm->vmcb->control is already cached in the 'control' local variable, so
use that.
