    39	 * Because the attribute value is a filename component, it will never be longer
    40	 * than 255 bytes. This means the attribute will always be a local format
    41	 * attribute as it is xfs_attr_leaf_entsize_local_max() for v5 filesystems will
    42	 * always be larger than this (max is 75% of block size).
    43	 *
    44	 * Creating a new parent attribute will always create a new attribute - there
    45	 * should never, ever be an existing attribute in the tree for a new inode.
    46	 * ENOSPC behavior is problematic - creating the inode without the parent
    47	 * pointer is effectively a corruption, so we allow parent attribute creation
    48	 * to dip into the reserve block pool to avoid unexpected ENOSPC errors from
    49	 * occurring.
