kthread_create_on_node - create a kthread.
2. SYNOPSIS ▲
struct task_struct * kthread_create_on_node(int (* threadfn ) (void *data), void * data , int node , const char namefmt , ... );
3. ARGUMENTS ▲
the function to run until signal_pending(current).
data ptr for threadfn.
memory node number.
printf-style name for the thread.
4. 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 Aqkthread_should_stopAq 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).
