Hi Dan,

Have you ever tested this code path?
    

Not this path, not yet.

You can disable the fallback to optimized synchronous functions and test
it with raid with dmaengine disabled. Or you can add support for
arbitrary coefficients in dmatest...

  Which is exactly why I am holding back the md
pieces.  We can collaborate on testing and stabilizing the api for a
kernel cycle before turning on the raid6 conversion.
  

Unfortunately we are not getting paid for this project any more so I
can't spend much time on it.

Regards, Ilya.
