Stefan,

The patch looks rather good, in particular the modifications to blockio
I had forgotten to check in the ubuntu kernel package.

But the point is that this very issue was already fixed - slightly

upstream repository. Hence my proposal of more collaboration instead of
this duplication of effort.

Arne
