Module stress 

Stress and edge-case scenario implementations.

Functions

custom_cgroup_cpuset_cross_llc_race

LLC-specific cpusets + tight flip loop. Uses Instant::now() deadline loop and LLC-aligned BTreeSets computed at runtime. Not Op/Step compatible.

custom_cgroup_cpuset_workload_variety

Uses spawn_diverse for workload variety + manual cpuset partitioning.

custom_cgroup_dsq_contention

Per-CPU pinned workers + custom gap assertion (max_gap_ms > 1500). Not expressible via Op/Step’s standard assert pipeline.

custom_cgroup_dynamic_workload_variety

spawn_diverse + dynamic cgroup add/remove mid-run.

custom_cgroup_exhaust_reuse

Exhaust cgroup slots with empty cpuset-pinned cgroups, remove half, then create replacement cgroups with workers to test slot reuse.

custom_cgroup_per_cpu

One cgroup per CPU, each with a single pinned worker. Stresses the scheduler with up to 64 cgroups on disjoint single-CPU cpusets.

custom_cgroup_workload_variety

Uses spawn_diverse helper for 5 different workload types across cgroups. Dynamic cgroup count and workload rotation logic is not Op/Step compatible.
