| Subject: rtmutex: Use chainwalking control enum |
| |
| In 8930ed80 (rtmutex: Cleanup deadlock detector debug logic), |
| chainwalking control enums were introduced to limit the deadlock |
| detection logic. One of the calls to task_blocks_on_rt_mutex was |
| missed when converting to use the enums. |
