Yes, it's a sweet little patch and has saved our ass a few times. It
would be nice if someone were to, umm, productize it and get it merged.
However, do see https://lkml.org/lkml/2009/4/1/137 where Ingo discusses
conversion to using the tracing infrastructure.
btw, the original patch was from the lost-lost and dearly missed
Alexander Nyberg <alexn@dsv.su.se>.
