As far as i saw they were still largely unanswered - but let me know if they are all answered and addressed: http://marc.info/?l=linux-kernel&m=117465220309006&w=2 http://marc.info/?l=linux-kernel&m=117489673929124&w=2 http://marc.info/?l=linux-kernel&m=117489831930240&w=2 and the numbers he posted: http://marc.info/?l=linux-kernel&m=117448900626028&w=2 his test conclusion was that under CPU load, RSDL (SD) generally does not hold up to mainline's interactivity.
