Subject: [linus:master] [hugetlb] 003af997c8: vm-scalability.throughput
-44.1% regression
Hello,
kernel test robot noticed a -44.1% regression of vm-scalability.throughput on:
commit: 003af997c8a945493859dd1a2d015cc9387ff27a ("hugetlb: force allocating surplus hugepages on mempolicy allowed nodes")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: vm-scalability
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz (Ice Lake) with 256G memory
parameters:
runtime: 300s
size: 512G
test: anon-w-rand-hugetlb
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
