In case it's useful to anyone, I rebased the series on top of v5.5-rc4. https://github.com/aubreyli/linux/tree/coresched_v4-v5.5-rc4
v5.5 includes a few scheduler rework and fix, so I modified patch1/2/6, patch-0002 has relatively big changes, but still has no functionality and logic change.
0001-sched-Wrap-rq-lock-access.patch 0002-sched-Introduce-sched_class-pick_task.patch 0003-sched-Core-wide-rq-lock.patch 0004-sched-Basic-tracking-of-matching-tasks.patch 0005-sched-A-quick-and-dirty-cgroup-tagging-interface.patch 0006-sched-Add-core-wide-task-selection-and-scheduling.patch 0007-sched-fair-Add-a-few-assertions.patch 0008-sched-Trivial-forced-newidle-balancer.patch 0009-sched-Debug-bits.patch 0010-sched-fair-wrapper-for-cfs_rq-min_vruntime.patch 0011-sched-fair-core-wide-vruntime-comparison.patch 0012-sched-fair-Wake-up-forced-idle-siblings-if-needed.patch
I verified by my test suites, it seems to work.
Thanks, -Aubrey
