The cgroup selftests lack a settings file, causing the kselftest runner
to apply its default 45s timeout. The test_cpu binary now exceeds this
limit, resulting in timeout failures that prevent the final test cases
from reporting results:
not ok 2 selftests: cgroup: test_cpu # TIMEOUT 45 seconds
Test execution times:
|Test | Duration |
|----------------------|-------------------- |
|cpu.weight (×4) | ~10s each |
|test_cpucg_stats | 2s CPU time |
|test_cpucg_nice | 2s CPU time |
|test_cpucg_max | 1000/HZ seconds |
|test_cpucg_max_nested | 1000/HZ seconds |
Total runtime: ~46s at HZ=1000, ~64s at HZ=100
When executed independently, all nine test cases complete
successfully (46.2s on a ppc64le HZ=1000 guest).
Introduce a settings file that increases the timeout to 120 seconds,
providing sufficient margin above the HZ=100 worst-case scenario.
