Values for min_granularity_ns and wakeup_granularity_ns read as 0

[calcastor]

Following #20 being merged, I've noticed that reading min_granularity_ns and wakeup_granularity_ns with cat shows their values as 0.

[root@81x2 ~]# cat /proc/sys/kernel/sched_cfs_bandwidth_slice_us /sys/kernel/debug/sched/latency_ns /sys/kernel/debug/sched/min_granularity_ns /sys/kernel/debug/sched/wakeup_granularity_ns
3000
12000000
0
0
[root@81x2 ~]# 

This was tested on Fedora 35 with secure boot disabled, which permits writing to the values. I do have it installed to /usr/local as opposed to /usr while also installing to sbin over bin following previous issues with a utility that set zen-kernel's CFS values, but I'm decently confident that this is not a contributing factor as the values read correctly prior to #20 with this same setup.

I'm not entirely sure something is wrong beyond those values showing as 0 as I do not seem to have had peformance regressions or otherwise.
