Hi,

Can we please hold off on this patch and the other PipeFS followups for
now? It isn't completely clear that people are hitting these problems in
the wild, and the patch itself introduces bugs which still aren't 100%
fixed upstream (I have 1 more patch queued to deal with the aftermath).

Let's just wait until we have definite proof that people are Oopsing,
and we've addressed all the issues in the upstream kernel.

Thanks,
  Trond
