It makes trying to open AttributesFile's B-tree during mount of HFS+ volume. If HFS+ volume hasn't AttributesFile then a pointer on AttributesFile's B-tree keeps as NULL. Thereby, when it is discovered absence of AttributesFile on HFS+ volume in the begin of xattr creation operation then AttributesFile will be created. The creation of AttributesFile will have success in the case of availability (2 * clump) free blocks on HFS+ volume. Otherwise, creation operation is ended with error (-ENOSPC).
