        will sigfault if `params == NULL`, how about

        <br>

             root->i_uid = (!params || params->fixed_uid < 0) ?

    <p>Hi Xiang,</p>

    <p>v3 patch sent, however I'm afraid we can't compare fixed_{u,g}id

      with 0,</p>

    <p>as it's of an unsigned type. I've kept ` params->fixed_uid ==

      -1` for now.</p>

    <p>Thanks,</p>
