Heya, I actually have no idea which bug you are talking about. TBH I'm only experiencing the bug fixed by b5b6e8c8d3b4, which only requires 2f31115e940c. (I tested a 4.14 with both commits which resolves the bug.) I doubt any of that would have any interference with aacraid and should be safe backports in that respect. Thanks, Felipe > > greg k-h
