hi, Ian Rogers,

we noticed this is a fix commit, and we really found some perf-sanity-tests
can pass on this commit now.
however, probe_libc's_inet_pton_&_backtrace_it_with_ping started to fail on this
commit.

        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.
