Hello,

kernel test robot noticed "kernel-selftests.openat2.resolve_test.fail" on:

commit: 58e2847ad2e6322a25dedf8b4549ff924baf8395 ("selftests: line buffer test program's stdout")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

in testcase: kernel-selftests
version: kernel-selftests-x86_64-60acb023-1_20230329
with following parameters:

	group: group-02

If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags

besides kernel-selftests.openat2.resolve_test, we also observed

which pass on parent commit.

however, there are other tests such like below "perf_events: sigtrap_threads"
are not impacted by this commit.

we want to consult with you if there is some special config need to do after
this commit? Thanks a lot!
