Subject: [PATCH] rtmutex: Use chainwalking control enum
Date: Tue, 15 Dec 2015 17:07:30 -0600 [thread overview]
Message-ID: <1450220850-31632-1-git-send-email-brad.mouring@ni.com> (raw)
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.
