      Description

      Parallel Directory Operation patch (LU-50, http://review.whamcloud.com/#change,375) will support 3-level directory which requires directory size over 2G, besides code change for htree of ext4/ldiskfs, we also need to use i_size_high to store size of directory. This requires change to e2fsprogs to make it understand it.
      We've added feature EXT4_FEATURE_RO_COMPAT_LARGEDIR to ldiskfs to prevent kernel/e2fsprogs that only support 2-level to modify 3-level directories, this should also be added to e2fsprogs.
