In case it's useful to anyone, I rebased the series on top of 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
