31 * Directory version 2.
32 * There are 4 possible formats:
33 * shortform
34 * single block - data with embedded leaf at the end
35 * multiple data blocks, single leaf+freeindex block
36 * data blocks, node&leaf blocks (btree), freeindex blocks
37 *
38 * The shortform format is in xfs_dir2_sf.h.
39 * The single block format is in xfs_dir2_block.h.
40 * The data block format is in xfs_dir2_data.h.
41 * The leaf and freeindex block formats are in xfs_dir2_leaf.h.
42 * Node blocks are the same as the other version, in xfs_da_btree.h.
