And I think there is another problem, your understanding and my understanding
of "clean" differ too much and it seems that we can not convince each other ;)

The last series looks buggy (I'll send more emails later today), but the
main problem is that - in my opinion! - your approach is "obviously wrong
and much less clean". But yes, yes, I understand that this is my opinion,
and I can be wrong.

Eric, I think we need more CC's. Linus, probably security list, the more
the better.

I am going to resend my series with more CC's, then you can nack it and
explain what you think we should do. Perhaps someone else will suggest
a better solution, or at least review the patches. OK?

Oleg.
