Subject: [linus:master] [kbuild]  3bc753c06d: xfstests.generic.454.fail


please be noted we felt quite strange why this change could cause
  xfstests.generic.454.fail
but even by rebuild and rerun, the issue seems persistent while keeping clean
on parent

           :10         100%          10:10    xfstests.generic.454.fail

so we just report out FYI to seek any insights about this.

(see /lkp/benchmarks/xfstests/results//generic/454.full for details)


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.
