[PATCH v3 0/2] sched_ext: Cgroup sub-scheduler minor fixes

[Zhao Mengmeng]

This patchset contains two fixes that I met when testing cgroup
sub-scheduler. Patch 1 add the -c option to scx_qmap help, which support
sub-scheduler but has no clue how to use it. Patch 2 add logs when sub-
scheduler is disabled, almost the same logic as root scheduler.

V3:
- Commit msg nit fix (Cheng-Yang Chou)
- Rebase on sched_ext/for_next(1d2c5353152d)

V2:
- Add [-c CG_PATH] to the usage synopsis(Cheng-Yang Chou)
