In addition to this I think it should be worth considering CC'ing Greg to pull this fix into 4.15 stable tree.
This isn't one he can cherry-pick, some munging required, in which case he usually wants a properly tested backport.

Maybe, this could be a good opportunity to push all the pending BFQ patches into the stable 4.15 branch? Because IIUC currently BFQ in 4.15 is just unusable.
Paolo?
Of course ok for me, and thanks Oleksandr for proposing this. These commits should apply cleanly on 4.15, and FWIW have been tested, by me and BFQ users, on 4.15 too in these months.
How does that work without someone actually submitting patches? CC stable and pass along a conveniently sorted cherry-pick list?
