+- * directly into the dispatch queue: the only active
+- * bfq_queues are bfqq and either its waker bfq_queue or one
+- * 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
+- * I/O directly in the dispatch list may evidently cause a

+- * splitting existing struct svm_ranges. All changes should be applied to
+- * the range_list and interval tree transactionally. If any split operation
+- * fails, the entire update fails. Therefore the existing overlapping
+- * svm_ranges are cloned and the original svm_ranges left unchanged. If the
+- * transaction succeeds, the modified clones are added and the originals
+- * freed. Otherwise the clones are removed and the old svm_ranges remain.
++ * If the transaction succeeds, the caller can update and insert clones and
++ * new ranges, then free the originals.
