It has been part of the -rt kernel for some time now and is deemed solid and useful enough to post in its own right. This contention should also occur on the large SMP machines. Feedback would be appreciated, especially with regard to the extra workqueue that was added to flush per cpu lists. Is there an alternative aproach?
