NAME
kthread_create - create a kthread.SYNOPSIS
- struct task_struct * kthread_create(int (*threadfn) (void *data), void * data, const char namefmt[], ...);
ARGUMENTS
threadfn
- the function to run until signal_pending(current).
data
- data ptr for threadfn.
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.
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).
