> Affects Versions: 3.1.1
> Reporter: Jinglun
> Priority: Minor

>
>
> DirectoryWithQuotaFeature.verifyQuotaByStorageType() does the job of
> verifying quota. It's redundant to call isQuotaByStorageTypeSet() because the
> for each iterator nextline has done the same job.
> {code:java}
> if (!isQuotaByStorageTypeSet()) { // REDUNDANT.
> return;
> }
> for (StorageType t: StorageType.getTypesSupportingQuota()) {
> if (!isQuotaByStorageTypeSet(t)) { // CHECK FOR EACH STORAGETYPE.
> continue;
> }
> if (Quota.isViolated(quota.getTypeSpace(t), usage.getTypeSpace(t),
> typeDelta.get(t))) {
> throw new QuotaByStorageTypeExceededException(
> quota.getTypeSpace(t), usage.getTypeSpace(t) + typeDelta.get(t), t);
> }
> }
> {code}
