    dx_dirs: fix return value of walk_dirblock() when enable metaecc

    If there is no error, the return value 'ret' might be used with
    undefined initial value. This patch fixes the error by initiating
    it to 0.

    dx_dirs: build indexed trees when enabling indexed-dirs

    Previos enable indexed-dirs implementation only set superblock flag,
    does not build indexed trees for existed directories.
    Tis patch tries to build indexed trees for directories when enable
    indexed-dirs.

    dx_dirs: add disable indexed-dirs support in tunefs.ocfs2

    This patch truncates all directories' indexed tree if '--fs-features
    noindexed-tree' option is given. The indexed dirs
    related flags on directory inodes and superblock are cleared too.

    dx_dirs: add 'blocknr' in callback of ocfs2_dir_iterate()

    In order to make ocfs2_dx_dir_insert() easier to set the dir block
    number to a dx record, a new parameter 'uint64_t
    blocknr' is added into the call back function parameter of
    ocfs2_dir_iterate(). This patch includes (part of) the
    related changes which are not mentioned in previous patches.

    dx_dirs: fsck.ocfs2 support

    This patch does a basic indexed dirs support in fsck.ocfs2.

    During pass2, if a directory block is changed, and indexed dirs in
    enabled, the indexed tree of this directory will be
    truncate, then rebuild with the modified directory data. All the
    modified directories' inode numbers are recored in a
    rb-tree, when all directories get scanned, truncate and rebuild the
    directories whose inode recorded in the rb-tree.

    dx_dirs: more library support for directory indexing

    This patch adds more library support for indexed dirs,
    - dx_root alloc/delete
    - dx_leaf alloc/delete
    - dx_root read/write
    - dx_leaf read/write
    - indexed tree insert/truncate
    - dx_root extent tree operations
    - indexed dir support in ocfs2_lookup_system_inode(),
      ocfs2_init_dir(), ocfs2_link(), ocfs2_unlink(),
      ocfs2_lookup().
    With this patch, indexed dirs support in fsck.ocfs2 is possible.

    dx_dirs: Add tunefs.ocfs2 feature for indexed directories

    dx_dirs: mkfs.ocfs2 support

    This adds only basic support to mkfs.ocfs2 to write the seed fields used
    in directory indexing. The feature string
    'indexed-dirs' is already there from a previous patch, so it is possible
    to create a new file system with the directory
    indexing feature turned on.

    Future improvements that are needed:

    - mkfs.ocfs2 should create the root directory and orphan dirs as
      indexed.
    - possibly also we want to do this for the system dir, but that might
      require some discussion.

    dx_dirs: debugfs.ocfs2 support

    This adds a full set of functionality to debugfs.ocfs2 so that we can
    visualize and debug indexed directories. Aside
    from updates to other commands to dump newly added/used fields in old
    structures, we get the following debugfs.ocfs2 commands:

    dx_space - Show all entries in the free list
    dx_dump  - Show the directory index (including root block)
    dx_leaf  - Show a single directory index leaf block
    dx_root  - Show directory index root block, as well as any extent blocks
               for non-inline dx_roots.

    dx_dirs: Add library support for directory indexing

    This patch updates ocs2_fs.h with the relevant directory indexing
    structures. Additionally, libocfs2/ is given swap
    functions for the new disk structures. The library also gets three new
    iteration functions:

    ocfs2_dx_entries_iterate() - to iterate all index entries in an inline,
    or external index.

    ocfs2_dx_frees_iterate() - an iterator for the dirblock free list.

    ocfs2_extent_iterate_dx_root() - iterate the extent blocks of an index
    tree.

    Caveats:

    Right now, this is all read-only. A major 'TODO' item is adding the
    appropriate API's to enable creation, deletion and
    various manipulation of the dx tree, as well as individual items.

    None of the other library code really knows about the directory index.
    This means that things like ocfs2_looup() is
    still using the old-style lookup via the unindexed dirent tree.

    We need to add support for the newly increased links_count maximum. This
    should probably be a seperate patch though.
