    ocfs2: make room for unwritten extents flag · e48edee2
    Mark Fasheh authored
    Due to the size of our group bitmaps, we'll never have a leaf node extent
    record with more than 16 bits worth of clusters. Split e_clusters up so that
    leaf nodes can get a flags field where we can mark unwritten extents.
    Interior nodes whose length references all the child nodes beneath it can't
    split their e_clusters field, so we use a union to preserve sizing there.
