Subject: [linus:master] [mm] c0bff412e6: stress-ng.clone.ops_per_sec -2.9%
regression
Hello,
kernel test robot noticed a -2.9% regression of stress-ng.clone.ops_per_sec on:
commit: c0bff412e67b781d761e330ff9578aa9ed2be79e ("mm: allow anon exclusive check over hugetlb tail pages")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: stress-ng
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
test: clone
cpufreq_governor: performance
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
