It can't be that simple if we're on v7 and at 11 patches!
It would be helpful if you included links to earlier postings. I can
only find v5 and v6 in my inbox, so I fear I'm going to re-ask some
questions which were already answered.
Why can't we shorten the names of these kthreads? You didn't
give any examples, so I can't suggest any possibilities.
