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,
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).
