The issue I reported does not exist in 4.14. \ I am going to verify the fix now. Hhmmm. Okay, I'll ask Komali to test this with the most complete bits available for 4.14.7. But it was my impression from talking to Komali that this got broken back in July with kernel.org:1455cf8 and has been broken ever since. I suppose the bisect she did could have missed a brief point where it wasn't broken.
