Upon reviewing the history of relevant commits, I found that they have been merged and reverted multiple times: ```bash git log -S 'cpumask_test_cpu(cpu, sched_domain_span(sd))' --oneline \ kernel/sched/fair.c 8aeaffef8c6e sched/fair: Take the scheduling domain into account in select_idle_smt() 3e6efe87cd5c sched/fair: Remove redundant check in select_idle_smt() 3e8c6c9aac42 sched/fair: Remove task_util from effective utilization in feec() c722f35b513f sched/fair: Bring back select_idle_smt(), but differently 6cd56ef1df39 sched/fair: Remove select_idle_smt() df3cb4ea1fb6 sched/fair: Fix wrong cpu selecting from isolated domain ``` The latest upstream commit 8aeaffef8c6e is not applicable to linux-4.19.y. The current patch has been tested on linux-4.19.y and I am looking forward to its inclusion in the stable version.
