Greeting,
FYI, we noticed the following commit (built with gcc-9):
commit: e655d17ffada57d11a82336a43fd91dd9c2ecbd2 ("[PATCH] mm: introduce sysctl file to flush per-cpu vmstat statistics")
url: https://github.com/0day-ci/linux/commits/Marcelo-Tosatti/mm-introduce-sysctl-file-to-flush-per-cpu-vmstat-statistics/20201118-002950
base: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git 9c87c9f41245baa3fc4716cf39141439cf405b01
in testcase: kernel-selftests
version: kernel-selftests-x86_64-b5a583fb-1_20201015
with following parameters:
group: group-02
ucode: 0xe2
test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt
on test machine: 4 threads Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz with 32G memory
