 kernel-selftests.rseq.run_param_test.sh.fail


Greeting,

FYI, we noticed kernel-selftests.rseq.run_param_test.sh.fail due to commit (built with gcc-11):

commit: b344b8f2d88dbf095caf97ac57fd3645843fa70f ("selftests/rseq: Add mm_numa_cid to test script")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git sched/core

in testcase: kernel-selftests
version: kernel-selftests-x86_64-2ed09c3b-1_20221128
with following parameters:

	group: rseq

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: 4 threads Intel(R) Xeon(R) CPU E3-1225 v5 @ 3.30GHz (Skylake) with 16G memory

# selftests: rseq: run_param_test.sh
# Default parameters
# Running test spinlock
# Running compare-twice test spinlock
# Running mm_cid test spinlock
# Running mm_cid compare-twice test spinlock
# Running mm_numa_cid test spinlock
# ./run_param_test.sh: line 52: ./param_test_mm_numa_cid: No such file or directory
not ok 10 selftests: rseq: run_param_test.sh # exit=1



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.
