Bug#695182: linux-image-3.2.0-4-686-pae: Write couple of 1GB files for OOM crash
Dear Ben,

What would you like me to call it instead? The machine seemed to
hang... do not know if rebooted spontaneously or in response to a
"shutdown -r now" that I had typed into an un-responsive xterm.

I did, and am convinced that bdi_position_ratio() now does the "right
thing": returns something within [0,2] mostly, and internally seems OK.
I think I had my "corrected" bdi_position_ratio() in use during this
latest OOM episode.

Thanks again for your prompt fix of bdi_position_ratio(). I will now
look for that elusive "next bug".
Cheers, Paul
