Greeting,

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

commit: edae34a3ed9293b5077dddf9e51a3d86c95dc76a ("selftests net: add UDP GRO fraglist + bpf self-tests")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

in testcase: kernel-selftests
version: kernel-selftests-x86_64-8d3977ef-1_20220523
with following parameters:

	group: net
	ucode: 0xec

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.
