3.14.61-rt63-rc1 stable review patch. If anyone has any objections, please let me know. ------------------ From: "bmouring@ni.com" 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.
