I think the cause is that scrub function allocates shadow inode for base inode

CInode.cc

    bool validate_directory_data() {
      assert(in->is_dir());

      if (in->is_base()) {
        shadow_in = new CInode(in->mdcache);
        in->mdcache->create_unlinked_system_inode(shadow_in,
                                                  in->inode.ino,
                                                  in->inode.mode);
        shadow_in->fetch(get_internal_callback(INODE));
        return false;
      } else {
        results->inode.passed = true;
        return check_dirfrag_rstats();
      }
    }
