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
