hi, Al Viro,

we noticed this commit there are lots of testcase: stress-ng
test machine: 64 parameters:

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

In addition to that,
+------------------+------ | testcase: change | test machine | test parameters | class=os | | | disk=1HDD | | fs=ext4 | | nr_threads=10% | | test=sysinfo | | testtime=60s +------------------+------

If you fix the issue the same patch/commit), | Reported-by: kernel | Closes: ========================== compiler/cpufreq_governor/ gcc-12/performance/x86_6
