Greeting,

FYI, we noticed the following commit (built with gcc-11):

commit: c9dc81ef10c33656280058c29dfaa1d549d1daee ("[PATCH 4/5 v1] mm: enable per numa node rss_stat count")

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.
