CELF Project Proposal/Add sleeping spinlocks to mainline kernel


 * 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 realtime preemption mini-summit, and the 2009 kernel summit.
