Right, I got busy with other stuff and it languished a bit.

I tried to merge it recently (it's actually in tip/sched/fifo atm), but
then 0day robot found a problem with it and I've not yet had the time to
deal with that.

Specifically these patches unEXPORT the schet_setscheduler() family, but
kernel/trace/ring_buffer_benchmark.c can still be a module :-(
