No. I heard your complaint about mixing "scope" and "cache_level".
Latest version of that code looks like this:
1341 unsigned int rdtgroup_cbm_to_size(struct rdt_resource *r,
1342 struct rdt_domain *d, unsigned long cbm)
1343 {
1344 struct cpu_cacheinfo *ci;

1346 int cache_level;
1347 int num_b, i;
1348
1349 switch (r->ctrl_scope) {
1350 case RESCTRL_L3_CACHE:
1351 cache_level = 3;
1352 break;
1353 case RESCTRL_L2_CACHE:
1354 cache_level = 2;
1355 break;
1356 default:
1357 WARN_ON_ONCE(1);
1358 return size;
1359 }
1360
1361 num_b = bitmap_weight(&cbm, r->cache.cbm_len);
1362 ci = get_cpu_cacheinfo(cpumask_any(&d->cpu_mask));
1363 for (i = 0; i < ci->num_leaves; i++) {
1364 if (ci->info_list[i].level == cache_level) {
1365 size = ci->info_list[i].size / r->cache.cbm_len * num_b;
1366 break;
1367 }
