RHEL 7.4 Resource -- Loading NETPRIO_CGROUP module and mounting it does not create default files

Latest response

With RHEL 7.4, after loading netprio_cgroup and sch_mqprio and mounting CGROUP, I was expecting default files listed below to be created under /sys/fs/cgroup/net_prio. But they do not get created.

cgroup.clone_children
cgroup.procs
net_prio.ifpriomap
notify_on_release
tasks
cgroup.event_control
cgroup.sane_behavior
net_prio.prioidx
release_agent

These are the steps I executed:
modprobe netprio_cgroup
modprobe sch_mqprio
mount -t tmpfs cgroup_root /sys/fs/cgroup
mkdir /sys/fs/cgroup/net_prio
mount -t cgroup -o net_prio none /sys/fs/cgroup/net_prio

On one of the RHEL 7.2 systems, it is working as expected. Any suggestions?

The issue is resolved. After some debugging it was found that with RHEL 7.4 net_prio cgroup sub-system need to be mounted with option

-o net_prio,net_cls instead of -o net_prio
