Subject: [PATCH 190/323] sched: Disable CONFIG_RT_GROUP_SCHED on RT
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.215-rt107.tar.xz

Carsten reported problems when running:

  taskset 01 chrt -f 1 sleep 1

from within rc.local on a F15 machine. The task stays running and
never gets on the run queue because some of the run queues have
rt_throttled=1 which does not go away. Works nice from a ssh login
shell. Disabling CONFIG_RT_GROUP_SCHED solves that as well.
