Looks like I could come up with the following https://github.com/jlelli/linux.git deadline/rework-cpusets https://github.com/jlelli/linux/tree/deadline/rework-cpusets which I don't think it's at a point that I feel comfortable to propose as an RFC (not even sure if it actually makes sense), but it survived my very light testing.
