Fedora 15 moving task (thread) off CPU

[Zach Wang]

Hi,
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.

Thank you.
