Subject: [PATCH v2 4/8] KVM: nSVM: Directly (re)calc vmcb02 intercepts from nested_vmcb02_prepare_control()
Date: Wed, 18 Feb 2026 15:09:54 -0800 [thread overview]
Message-ID: <20260218230958.2877682-5-seanjc@google.com> (raw)
In-Reply-To: <20260218230958.2877682-1-seanjc@google.com>
Now that nested_vmcb02_recalc_intercepts() provides guardrails against it
being incorrectly called without vmcb02 active, invoke it directly from
nested_vmcb02_recalc_intercepts() instead of bouncing through
svm_mark_intercepts_dirty(), which unnecessarily marks vmcb01 as dirty.
