> For a directory that doesn't have any storage policy defined, its storage quota usage
is deducted when a file is deleted (addBlock skips storage quota usage update in such case).
This means negative value for storage quota usage. Later after applications set the storage
policy and storage type quota, it allows the applications to use more than its storage type
quota.
