OK. So we want to create a thread that is a child of kthreadd, but inherits the cgroup/cpumask
from the caller. How about an exported kthread function kthread_create_in_current_cg()
that does this?
     

Well. I must admit, this looks a bit strange to me ;)

Instead of exporting sched_xxxaffinity() we export the new function
which calls them. And I don't think this new helper is very useful
in general. May be I am wrong...
   

If we agree on exporting sched_xxxaffinity() functions, we don't need 
this new kthread function and we
can do the same in vhost as the original patch did.

Thanks
