FYI, we noticed the following commit (built with gcc-7):

commit: 100c2d1c348d3a0499b635a79d22518326a00619 ("perf: change strncpy+truncation to strlcpy") https://github.com/0day-ci/linux UPDATE-20180720-104941/Dominique-Martinet/coccinelle-change-strncpy-truncation-to-strlcpy/20180714-082532

in testcase: perf-sanity-tests
with following parameters:

perf_compiler: gcc



on test machine: qemu-system-x86_64 -enable-kvm -cpu kvm64,+ssse3 -smp 2 -m 8G

caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
