This is a known issue that's going to be addressed in future release.

Quoting Igor:

"I will return to sched_setaffinity after cache will be done.
Current sched_setaffinity() processing needs to be rewritten:
1) it does not support RedHat sched_setaffinity() interface,
2) it should use CPU_SET()/etc interface for other Linuxes."
