I'm trying to move kernel threads off CPUs, but can't seem to do so in F15. The kernel call used is sched_setaffinity, and it fails with message "Invalid argument". Example threads include "cpuset" and "khelper", among others. Yes, I have checked that these threads are not bounded to specific CPUs. Any idea why? Are there any new restrictions w.r.t. moving kthreads in F15? There were no problems in Redhat 6 or earlier.
