## Description

From tw setup, I can see below error on sysctl test:

# Test messages # Sysctl_kernel_sched_child_runs_first
# failure: 

255 - sysctl: cannot stat /proc/sys/kernel/sched_child_runs_first: No such file or directory

The issue is not seen on sle15sp6 [the int value is '0']

Is it a new kernel feature or a product bug?


## Observation

openQA test in scenario opensuse-Tumbleweed-DVD-x86_64-sys-param-check@64bit fails in
[Sysctl](https://openqa.opensuse.org/tests/4241601/modules/Sysctl/steps/135)

## Test suite description
RAM size is set to 2048, some kernel parameters change with total RAM https://github.com/openSUSE/sys-param-check


## Reproducible

Fails since (at least) Build [20230910](https://openqa.opensuse.org/tests/3565003)


## Expected result

Last good: [20230908](https://openqa.opensuse.org/tests/3562695) (or more recent)


## Further details

Always latest result in this scenario: [latest](https://openqa.opensuse.org/tests/latest?arch=x86_64&distri=opensuse&flavor=DVD&machine=64bit&test=sys-param-check&version=Tumbleweed)
