NAME
       kthread_create_on_node - create a kthread.

SYNOPSIS
       struct task_struct * kthread_create_on_node(int (*threadfn) (void *data), void * data, int node, const char namefmt[], ...);

ARGUMENTS
       threadfn
	   the function to run until signal_pending(current).

       data
	   data ptr for threadfn.

       node
	   memory node number.

       namefmt[]
	   printf-style name for the thread.

       ...
	   variable arguments

DESCRIPTION
       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.

       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 -1. 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).
