Hmmm ... ok I suppose.

Could we have the kernel/sched.c code, in this case, call the
kernel/cpuset.c routine async_rebuild_sched_domains(), rather
than the synchronous rebuild_sched_domains() call (in your naming)
which required details of the get_online_cpus() and put_online_cpus()
wrapping to leak into kernel/sched.c:arch_reinit_sched_domains()
routine?
