Message-ID: <CAK7LNARXgaWw3kH9JgrnH4vK6fr8LDkNKf3wq8NhMWJrVwJyVQ@mail.gmail.com> Date: Tue, 21 May 2024 02:34:50 +0900 From: Masahiro Yamada <masahiroy@...nel.org> To: Steven Rostedt <rostedt@...dmis.org>, Linux Kernel Mailing List <linux-kernel@...r.kernel.org> Subject: ftrace/test_ownership kselftest fails in the second run Hi Steven, If I execute test.d/00basic/test_ownership.tc in a row, it passes in the first run, and fails in the second run. I observe this on the Ubuntu 24.04 (6.8 kernel), and also on the latest linux-next (next-20240520). Is this a limitation of the test or a kernel bug? vagrant@...ian:~/linux/tools/testing/selftests/ftrace$ sudo /ftracetest test.d/00basic/test_ownership.tc unlink: cannot unlink '/home/vagrant/linux/tools/testing/selftests/ftrace/logs/latest': No such file or directory === Ftrace unit tests === [1] Test file and directory ownership changes for eventfs [PASS] # of passed: 1 # of failed: 0 # of unresolved: 0 # of untested: 0 # of unsupported: 0 # of xfailed: 0 # of undefined(test bug): 0 vagrant@...ian:~/linux/tools/testing/selftests/ftrace$ sudo /ftracetest test.d/00basic/test_ownership.tc === Ftrace unit tests === [1] Test file and directory ownership changes for eventfs [FAIL] # of passed: 0 # of failed: 1 # of unresolved: 0 # of untested: 0 # of unsupported: 0 # of xfailed: 0 # of undefined(test bug): 0 vagrant@...ian:~/linux/tools/testing/selftests/ftrace$ uname -r 6.9.0-next-20240520 -- Best Regards Masahiro Yamada
