Summary: add sleeping spinlocks to the mainline kernel

Proposer: Tim Bird

Description:
One of the last major elements of the RT-preempt patch set that is
still not mainlined is the implementation of the so-called
"sleeping spinlocks".  It would be good to mainline these,
addressing remaining issues to their inclusion in the standard
Linux kernel.

Thomas Gleixner discussed the status of RT-preempt at the
[http://lwn.net/Articles/354690/ realtime preemption mini-summit,
and the [http://lwn.net/Articles/357465/ 2009 kernel summit].
