Dunno.  kthread_create_with_memory_on_node() :)

How's about kthread_create_for_node()?  That's sufficiently vague to
not mislead readers into thinking that it schedules the thread on that
CPU and leaves room in the namespace for a real kthread_create_on_cpu()
(which we could well end up creating).

kthread_create_node_mem()?

True, but what we're doing here is specifying on which node the
kthread's memory resources should reside - we need to do that even for
CPUs which live on memoryless nodes.
