KTHREAD_STOP(9) 						   Driver Basics						   KTHREAD_STOP(9)

NAME
       kthread_stop - stop a thread created by kthread_create.

SYNOPSIS
       int kthread_stop(struct task_struct * k);

ARGUMENTS
       k
	   thread created by kthread_create.

DESCRIPTION
       Sets kthread_should_stop for k to return true, wakes it, and waits for it to exit. This can also be called after kthread_create instead of
       calling wake_up_process: the thread will exit without calling threadfn.

       If threadfn may call do_exit itself, the caller must ensure task_struct can't go away.

       Returns the result of threadfn, or -EINTR if wake_up_process was never called.
