 Description   

In mdd_migrate_update_name()

        if (ldata->ld_buf != NULL) {
                rc = mdd_update_linkea(env, mdd_pobj, mdd_sobj, mdd_tobj,
                                       handle, lname, ldata);
                if (rc != 0)
                        GOTO(stop_trans, rc);
                          --------------> Since mdd_update_linkea might change the link of source file, we should re_get attr, otherwise the following DELETE lovEA might check with wrong nlink.  
        }

        if (S_ISREG(so_attr->la_mode)) {
                if (so_attr->la_nlink == 1) {
                        rc = mdo_xattr_del(env, mdd_sobj, XATTR_NAME_LOV,
                                           handle);
                        if (rc != 0 && rc != -ENODATA)
                                GOTO(stop_trans, rc);

                        rc = mdo_xattr_set(env, mdd_tobj, NULL,
                                           XATTR_NAME_FID,
                                           LU_XATTR_REPLACE, handle);
                        if (rc < 0)
                                GOTO(stop_trans, rc);
                }
        }
