Subject: [patch 0/2] rtmutex: Fix the deadlock detector for real
Date: Wed, 14 May 2014 20:03:26 -0000	[thread overview]
Message-ID: <20140514195705.618583609@linutronix.de> (raw)

Lai pointed out that the chain walk is incomplete aside of not
detecting even the simple AA deadlock.

The following series contains:

1) The fix for this, which replaces the hot fix I send out earlier

2) An optimization to avoid pointless de/enqueue operations in the
   deadlock chain walk

Thanks,

	tglx
