37 * Parent pointer attribute handling.
38 *
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.
