cgroup_regression_test 7 TBROK: 'tst_cgctl require files' failed. LTP missing files controller support?

[rengx]

Missing support for the "files" controller in LTP causes the "cgroup_regression_test.sh" test to fail.
In my test environment:

• kernel version: 6.6.0, and the last entry in /proc/cgroups is "files"
• LTP version: 20250530

How exactly does the test fail? Can you include an error messages?

[rengx]

Thanks.
There are all of the error messages, and this issue is likely the same as #1038.
