Nobody said you wrote the documentation, but you do maintain code which 
disobeys the documented DMA API & now you're being an ass about it 
unnecessarily.

Nobody said that you are required to do anything, I suggested that it would be 
beneficial if you were to suggest a change to the documented DMA API such that 
it allows your usage where it currently does not. If you don't want to have 
any input into that, and you actually think that your current approach of 
ignoring the documented API is the best path forwards, then we're probably 
done here & I'll be making a note to avoid yourself & anything under net/ to 
whatever extent is possible...

Thanks,
    Paul
