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
data
node
namefmt[]
...
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, kthread_create_on_cpu.
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 noone 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).
