Subject: [linus:master] [memcg] 70a64b7919: stress-ng.shm.ops_per_sec -8.5% regression

hi, Shakeel,

besided what we reported testcase: stress-ng
test machine: 64 parameters:

nr_threads: 100%
testtime: 60s
test: shm
cpufreq_governor: performance

In addition to that,
+------------------+------ | testcase: change | test machine | test parameters | | nr_threads=100% | | test=bigheap | | testtime=60s +------------------+------ | testcase: change | test machine | test parameters | | mode=process | | nr_task=100% | +------------------+------

If you fix the issue the same patch/commit), | Reported-by: kernel | Closes: ========================== compiler/cpufreq_governor/ gcc-13/performance/x86_6
