+-	 * of its woken bfq_queues. The rationale behind this
+-	 * additional condition is as follows:
+-	 * - consider a bfq_queue, say Q1, detected as a waker of
+-	 *   another bfq_queue, say Q2
+-	 * - by definition of a waker, Q1 blocks the I/O of Q2, i.e.,
+-	 *   some I/O of Q1 needs to be completed for new I/O of Q2
+-	 *   to arrive.  A notable example of waker is journald
+-	 * - so, Q1 and Q2 are in any respect the queues of two
+-	 *   cooperating processes (or of two cooperating sets of
+-	 *   processes): the goal of Q1's I/O is doing what needs to
+-	 *   be done so that new Q2's I/O can finally be
+-	 *   issued. Therefore, if the service of Q1's I/O is delayed,
+-	 *   then Q2's I/O is delayed too.  Conversely, if Q2's I/O is
+-	 *   delayed, the goal of Q1's I/O is hindered.
+-	 * - as a consequence, if some I/O of Q1/Q2 arrives while
+-	 *   Q2/Q1 is the only queue in service, there is absolutely
+-	 *   no point in delaying the service of such an I/O. The
+-	 *   only possible result is a throughput loss
+-	 * - so, when the above condition holds, the best option is to
+-	 *   have the new I/O dispatched as soon as possible
+-	 * - the most effective and efficient way to attain the above
+-	 *   goal is to put the new I/O directly in the dispatch
+-	 *   list
+-	 * - as an additional restriction, Q1 and Q2 must be the only
+-	 *   busy queues for this commit to put the I/O of Q2/Q1 in
+-	 *   the dispatch list.  This is necessary, because, if also
+-	 *   other queues are waiting for service, then putting new
