    Subject[PATCH 28/39] ocfs2: Determine an extent tree's max_leaf_clusters in an et_op.
    Date
    From: Joel Becker <joel.becker@oracle.com>

    Provide an optional extent_tree_operation to specify the
    max_leaf_clusters of an ocfs2_extent_tree. If not provided, the value
    is 0 (unlimited).
