Thanks!

But are you aware that the code on that branch doesn't build?

$ make all
[ ... ]
ERROR: "bfq_mark_bfqq_busy" [block/bfq-wf2q.ko] undefined!
ERROR: "bfqg_stats_update_dequeue" [block/bfq-wf2q.ko] undefined!
[ ... ]

$ PAGER= git grep bfq_mark_bfqq_busy
block/bfq-wf2q.c:       bfq_mark_bfqq_busy(bfqq);
