Subject: [patch 0/2] rtmutex: Sanitze deadlock detection and chain walk
Date: Thu, 05 Jun 2014 15:28:32 -0000	[thread overview]
Message-ID: <20140605152544.641846795@linutronix.de> (raw)

Brad found a flaw in the dead lock detection logic when the lock chain
changes during the chain walk and tried to fixup the deadlock detector
itself.

The following patches address this issue in a different way. Instead
of guessing about the chain change, simply detect it.

Thanks,

	tglx
