Greeting, FYI, we noticed a -8.7% regression of vm-scalability.throughput due to commit: commit: 85b9f46e8ea451633ccd60a7d8cacbfff9f34047 ("mm, thp: track fallbacks due to failed memcg charges separately") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: vm-scalability on test machine: 104 threads Skylake with 192G memory with following parameters: runtime: 300s size: 1T test: lru-shm cpufreq_governor: performance ucode: 0x2006906 test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us. test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/ If you fix the issue, kindly add following tag Reported-by: kernel test robot Details
