I'm pretty sure this wasn't a "regression" and was always there, and
that the proposed patch did fix the solution, right Paulo and Alan?

I'm also pretty sure that it's not a regression and that the patch
should have fixed it. But since Paolo hasn't replied to any of our
queries, we can't be certain.

No I haven't fix the problem... I'am waiting for a friend that is in
holiday's and work's with linux well. I'am beginer in linux and I can't put
the patch to work, because of that I'am waiting for him to see if the patch
work.
Sorry, the fact I don't say anything about the problem but my friend comes
this week and them we put the patch and I will tell something!!
Regards, Paulo.

Ok, it's queued up for after 2.6.22 is out as it is not a regression and
is kind of intrusive.

Unless others think it should go in now?
