After doing a little research, let me suggest this wording: /* * The "early" parameter can be true only if old-style AMD * Opteron NUMA detection is enabled, which should never be * the case for an SEV-SNP guest. See CONFIG_AMD_NUMA. * For safety, just do nothing if "early" is true. */ Let me know if this new wording makes sense based on your understanding. Michael > + if (early) > + return; > +
