Many thanks for pointing this out!

Strange enough, nobody seems to care. I have carefully read Ross Andersons
report, and I'm more than concerned now. Because I'm not a kernel
programmer, I can not see by myself what these patches will do to the Linux
kernel at all, so I can only hope that Linus will not let them in if they 
can be misused to what Ross Anderson describes in his paper.

Regards,
Heinz.
