Subject: [patch V3 0/7] rtmutex: Code clarification and optimization
Date: Mon, 09 Jun 2014 20:28:06 -0000	[thread overview]
Message-ID: <20140609201118.387571774@linutronix.de> (raw)

This is another round of clarification and optimization patches for
the rtmutex code.

When I looked last week into the dead lock detector I spent some time
to figure out how the various arguments and local variables are
protected and whats the scope of the various protection algorithms, so
I added documentation for this as well.

I also changed the last patch which avoids the requeueing in case of
the deadlock detection only chain walk. Instead of adding tons of
conditional to the boost/deboost code path I simply have a separate
code path for it.

Thanks,

	tglx
