Mainline RT-preempt patchset
Tim Bird


The RT-preempt patch set provides real-time scheduling performance for Linux. Parts of this patch set have been mainlined over time, but there are still significant parts that remain out-of-tree.

This project would consist of mainlining the remaining portions of the RT-preempt patch set, to avoid integration costs for those companies that use this patchset, and to decrease the maintenance cost of the patchset.

Probably measured in man-years. Would be good to define intermediate milestones for progress, and work towards those.
