6   This function can be used as <em class="parameter"><code>threadfn</code></em> to <code class="function">kthread_create</code> or
7   <code class="function">kthread_run</code> with <em class="parameter"><code>worker_ptr</code></em> argument pointing to an initialized
8   kthread_worker.  The started kthread will process work_list until
9   the it is stopped with <code class="function">kthread_stop</code>.  A kthread can also call
10   this function directly after extra initialization.
11   </p><p>
12
13   Different kthreads can be used for the same kthread_worker as long
14   as there's only one kthread attached to it at any given time.  A
15   kthread_worker without an attached kthread simply collects queued
16   kthread_works.
