Acked-by: Roland McGrath <roland@...hat.com>

Indeed the old code was highly suspect and we need more work to fix it.
But this was not a conservative change and it did produce regressions.
It's better to leave old-and-wrong as it was until we have finished
more thorough revamp work.


Thanks,
Roland
