    kernel: workqueue: Mention the default queue
    In the slide we talked about queue_work() (for queueing a work in a
    specific queue) and used schedule_work() in the example without
    mentioning its purpose (the use of a default queue). Add a mention to it
    in the explanation.
    Reduce a little bit the size of the minted block in order to fit in the

   \item A workqueue, usually allocated in a per-device structure,
     is registered with \kfunc{INIT_WORK} and typically
-    triggered with \kfunc{queue_work}
+    triggered with \kfunc{queue_work} when using a dedicated queue or
+    \kfunc{schedule_work} when using the default queue
   \item The complete API, in \kfile{include/linux/workqueue.h}, provides
     many other possibilities (creating its own workqueue threads, etc.)
   \item Example (\kfile{drivers/crypto/atmel-i2c}):
 INIT_WORK(&work_data->work, atmel_i2c_work_handler);
