Subject: [selftests/vm] c5fac7744c:
kernel-selftests.vm.run_vmtests.sh../hugepage_mmap.fail
Greeting,
FYI, we noticed the following commit (built with gcc-11):
commit: c5fac7744cf417920552cb4eec2600fb53048b0b ("[RFC PATCH] selftests/vm: enable running select groups of tests")
url: https://github.com/intel-lab-lkp/linux/commits/Joel-Savitz/selftests-vm-enable-running-select-groups-of-tests/20220610-082232
base: https://git.kernel.org/cgit/linux/kernel/git/shuah/linux-kselftest.git next
patch link: https://lore.kernel.org/lkml/20220610002046.3243874-1-jsavitz@redhat.com
in testcase: kernel-selftests
version: kernel-selftests-x86_64-cebf67a3-1_20220612
with following parameters:
sc_nr_hugepages: 2
group: vm
ucode: 0xec
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: 12 threads 1 sockets Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz with 16G memory
caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
please be noted, besides kernel-selftests.vm.run_vmtests.sh../hugepage_mmap.fail,
we actually observed other tests failed on this commit but pass on parent.
here we list all tests run on both parent and the commit, even they have
same results. FYI

To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.
