kthread_create_on_node — create a kthread.

threadfnthe function to run until signal_pending(current).
data
data ptr for threadfn.
nodetask and thread structures for the thread are allocated on this node
namefmt[]printf-style name for the thread.
...variable arguments
This helper function creates and names a kernel
thread. The thread will be stopped: use wake_up_process to start
it. See also kthread_run. The new thread has SCHED_NORMAL policy and
is affine to all CPUs.
If thread is going to be bound on a particular cpu, give its node
in node, to get NUMA affinity for kthread stack, or else give NUMA_NO_NODE.
When woken, the thread will run threadfn() with data as its
argument. threadfn() can either call do_exit directly if it is a
standalone thread for which no one will call kthread_stop, or
return when 'kthread_should_stop' is true (which means
kthread_stop has been called). The return value should be zero
or a negative error number; it will be passed to kthread_stop.
Returns a task_struct or ERR_PTR(-ENOMEM) or ERR_PTR(-EINTR).
