| Subject: [PATCH 07/12] RH: warn on invalid regex instead of failing |
| |
| multipath.conf used to allow "*" as a match everything regular expression, |
| instead of requiring ".*". Instead of erroring when the old style |
| regular expressions are used, it should print a warning and convert |
| them. |
