It is otherwise unchanged from .311. http://ck.kolivas.org/patches/bfs/2.6.32-sched-bfs-312.patch A quick set of kernbench benchmarks on my quad core: http://ck.kolivas.org/patches/bfs/kernbench2.6.32BFSvCFS.log Note one person has had problems with preemptible tree based hierarchical rcu and bfs 311 using high amounts of CPU, the cause of which remains unknown at the moment. Probably safest to not use this combination for now.
