It's not clear why there needs to be a new syscall. sched_setscheduler() already exists, and it's struct sched_param argument can be extended to include parameters specific to particular scheduler policies.

Well, extending struct sched_param is more than possible, I agree, but it would be a _really_big_ ABI issue, don't you think?
Especially when a 'legacy' binary comes to, e.g., a sched_getparam, and the data it gets will be bigger than expected... :-(
