+ * - RN_IDX - Running index. Index of the tail of the list.

+ * Locking:
+ * The linked list assumes jctx.lock is held.
+ * The ringbuffer serves as an intermediary between irq context and non-irq
+ * context, without the need for the two to share any lock. irq context can
+ * pull (and unpull) and only requires the runpool_irq.lock. While non-irq
+ * context can add and remove and only requires holding only jctx.lock.
+ * Error handling affecting both, or the whole ringbuffer in general, must
+ * hold both locks or otherwise ensure (f.ex deschedule/kill) only that thread
+ * is accessing the buffer.
+ * This means that RD_IDX is updated by irq-context (pull and unpull) and must
+ * hold runpool_irq.lock. While WR_IDX (add) and RN_IDX (remove) is updated by
+ * non-irq context and must hold jctx.lock.
+ * Note that pull (or sister function peek) must also access WR_IDX to ensure
+ * there is free space in the buffer, this is ok as WR_IDX is only increased.
+ * A similar situation is apparent with unpull and RN_IDX, but only one atom
+ * (already pulled) can cause either remove or unpull, so this will never
+ * conflict.
+ *
+ * &struct jsctx_queue is a queue of &struct kbase_jd_atom,
+ * part ringbuffer and part linked list.
