For this particular code, any objection to using early returns to reduce indentation? The else branch above is a bit gnarly, especially when legacy_gpat_semantics comes along. I.e. end up with this static void svm_set_pat(struct kvm_vcpu *vcpu, bool from_host, u64 data) { struct vcpu_svm *svm = to_svm(vcpu); if (svm_pat_accesses_gpat(vcpu, from_host)) { vmcb_set_gpat(svm->vmcb, data); return; } svm->vcpu.arch.pat = data; if (!npt_enabled) return; vmcb_set_gpat(svm->vmcb01.ptr, data); if (is_guest_mode(&svm->vcpu) && (svm->nested.legacy_gpat_semantics || !nested_npt_enabled(svm))) vmcb_set_gpat(svm->vmcb, data); } I can fixup when applying (unless you and/or Yosry object).
