Hi all,
The livepatch selftest somehow fails in -next on s390 due to what
appears to me as 'comm' usage issue. E.g the removal of timestamp-
less line "with link type OSD_10GIG." in the below output forces
'comm' to produce the correct result in check_result() function of
tools/testing/selftests/livepatch/functions.sh script:
[ 11.229256] qeth 0.0.bd02: qdio: OSA on SC 2624 using AI:1 QEBSM:0 PRI:1 TDD:1 SIGA: W

By contrast, using the 'diff' instead works as a charm. But it was
removed with commit 2f3f651f3756 ("selftests/livepatch: Use "comm"
instead of "diff" for dmesg").
I am attaching the contents of "$expect" and "$result" script
variables and the output of 'dmesg' before and after test run
dmesg-saved.txt and dmesg.txt.
Another 'dmesg' output dmesg-saved1.txt and dmesg1.txt also
shows the same problem, which seems like something to do with
sorting.
The minimal reproducer attached is dmesg-saved1-rep.txt and
dmesg1-rep.txt, that could be described as:
--- dmesg-saved1-rep.txt 2023-12-17 21:08:14.171014218 +0100
+++ dmesg1-rep.txt 2023-12-17 21:06:52.221014218 +0100

-[ 98.820331] livepatch: 'test_klp_state2': starting patching transition

[ 284.224335] livepatch: kernel.ftrace_enabled = 1
+[ 284.232921] ===== TEST: basic shadow variable API =====
The culprit is the extra space in [ 98.820331] timestamp, that from
the script point of view produces the output with two extra lines:
[ 100.031067] livepatch: 'test_klp_state2': completing patching transition
[ 284.224335] livepatch: kernel.ftrace_enabled = 1
[ 284.232921] ===== TEST: basic shadow variable API =====
If the line with [ 98.820331] timestamp removed or changed to e.g
[ 100.031066] (aka 1 us less), then the result output is as expected:
[ 284.232921] ===== TEST: basic shadow variable API =====
Thanks!
