Sascha is wasting his time by reinventing the wheel.  He's traveling
over exactly the same path I have already covered.  In fact, some of
his reviewer comments are almost word-for-word the same as those I
have received and addressed in the past.

My patches were always kept current in this mailing list and others,
and Sascha clearly has the skills necessary to make improvements and
corrections should he have chosen to do so.

That's a real duplication of work.  That makes no sense.

My code has already moved past that point.  And if I had the time to
evaluate and improve Sascha's patches, I would have the time to finish
my own.  Sascha is more than welcome to apply his efforts to the
preexisting PWM API patches already present in the LKML archives.

Annoyed isn't the word you are looking for.

My code has been reviewed, tested and actively used as posted in LKML
by several reviewers (including myself) in actual hardware.  We are
consciously choosing to discard a known entity and restart the whole
process with new code.  That's a waste of everyone's time and risk
exposure.

I don't consider Sascha's code to be "competing" with mine, as
apparently nobody has bothered to consider one against the other.

Your definition of "promsing" apparently correlates with "new and shiny".
