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

[test failed on linus/master 0bb80ecc33a8fb5a682236443c1e740d5c917d1d] [test failed on linux-next/master 7bc675554773f09d88101bf1ccfc8537dc7c0be9]

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

group: group-02

compiler: gcc-12 test machine: 36 threads 1 sockets Intel(R) Core(TM) i9-10980XE CPU @ 3.00GHz (Cascade Lake) with 32G memory

(please refer to attached dmesg/kmsg for entire log/backtrace)

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 | Reported-by: kernel test robot oliver.sang@intel.com | Closes: https://lore.kernel.org/oe-lkp/202309121342.97e2f008-oliver.sang@intel.com

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

ea09800bf17561a0 58e2847ad2e6322a25dedf8b454 ---------------- --------------------------- fail:runs %reproduction fail:runs | | | :6 100% 6:6 kernel-selftests.openat2.openat2_test.fail :6 100% 6:6 kernel-selftests.openat2.resolve_test.fail

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!
