kthread_create — create a kthread.
struct task_struct * kthread_create ( | int (* | threadfn(void *data), |
| void * | data, | |
| const char | namefmt[], | |
...); |
threadfnthe function to run until signal_pending(current).
data
data ptr for threadfn.
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, kthread_create_on_cpu.
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).
