| Subject: [PATCH] selftests/ftrace: Return unsupported if no error_log file |
| |
| commit 619ee76f5c9f6a1d601d1a056a454d62bf676ae4 upstream. |
| |
| Check whether error_log file exists in tracing/error_log testcase |
| and return UNSUPPORTED if no error_log file. |
| |
| This can happen if we run the ftracetest on the older stable |
| kernel. |
