      Description

      This can happen when migrate directory MDT-object_A's metadata from MDT_x to MDT_y: all object_A's children name entries needs to be moved to MDT_y. If some name entry originally referenced a remote MDT-object_B which was linked under "/REMOTE_PARENT_DIR" with a dummy name entry on MDT_y, but after the migration, the MDT-object_B and its new name entry resides on the same MDT_y, then the dummy entry for the MDT-object_B should be removed from "/REMOTE_PARENT_DIR".

      The LFSCK should guarantee that related inconsistency can be detected and repaired in spite of whether DEN has handled such case successfully or not.
