| Subject: [PATCH] tools lib traceevent: Fix "robust" test of |
| do_generate_dynamic_list_file |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| commit 82a2f88458d70704be843961e10b5cef9a6e95d3 upstream. |
| |
| The tools/lib/traceevent/Makefile had a test added to it to detect a failure |
| of the "nm" when making the dynamic list file (whatever that is). The |
| problem is that the test sorts the values "U W w" and some versions of sort |
| will place "w" ahead of "W" (even though it has a higher ASCII value, and |
| break the test. |
| |
| Add 'tr "w" "W"' to merge the two and not worry about the ordering. |
