+======================================================
+A Tour Through TREE_RCU's Grace-Period Memory Ordering
+======================================================
+
+August 8, 2017
+
+This article was contributed by Paul E. McKenney
+
+Introduction
+============
+
+This document gives a rough visual overview of how Tree RCU's
+grace-period memory ordering guarantee is provided.
+
+What Is Tree RCU's Grace Period Memory Ordering Guarantee?
+==========================================================
+
+RCU grace periods provide extremely strong memory-ordering guarantees
+for non-idle non-offline code.
+Any code that happens after the end of a given RCU grace period is guaranteed
+to see the effects of all accesses prior to the beginning of that grace
+period that are within RCU read-side critical sections.
+Similarly, any code that happens before the beginning of a given RCU grace
+period is guaranteed to not see the effects of all accesses following the end
+of that grace period that are within RCU read-side critical sections.
+
+Note well that RCU-sched read-side critical sections include any region
+of code for which preemption is disabled.
+Given that each individual machine instruction can be thought of as
+an extremely small region of preemption-disabled code, one can think of
+``synchronize_rcu()`` as ``smp_mb()`` on steroids.
+
+RCU updaters use this guarantee by splitting their updates into
+two phases, one of which is executed before the grace period and
+the other of which is executed after the grace period.
+In the most common use case, phase one removes an element from
+a linked RCU-protected data structure, and phase two frees that element.
+For this to work, any readers that have witnessed state prior to the
+phase-one update (in the common case, removal) must not witness state
+following the phase-two update (in the common case, freeing).
+
+The RCU implementation provides this guarantee using a network
+of lock-based critical sections, memory barriers, and per-CPU
+processing, as is described in the following sections.
+
+Tree RCU Grace Period Memory Ordering Building Blocks
+=====================================================
+
+The workhorse for RCU's grace-period memory ordering is the
+critical section for the ``rcu_node`` structure's
+``->lock``. These critical sections use helper functions for lock
+acquisition, including ``raw_spin_lock_rcu_node()``,
+``raw_spin_lock_irq_rcu_node()``, and ``raw_spin_lock_irqsave_rcu_node()``.
+Their lock-release counterparts are ``raw_spin_unlock_rcu_node()``,
+``raw_spin_unlock_irq_rcu_node()``, and
+``raw_spin_unlock_irqrestore_rcu_node()``, respectively.
+For completeness, a ``raw_spin_trylock_rcu_node()`` is also provided.
+The key point is that the lock-acquisition functions, including
+``raw_spin_trylock_rcu_node()``, all invoke ``smp_mb__after_unlock_lock()``
+immediately after successful acquisition of the lock.
+
+Therefore, for any given ``rcu_node`` structure, any access
+happening before one of the above lock-release functions will be seen
+by all CPUs as happening before any access happening after a later
+one of the above lock-acquisition functions.
+Furthermore, any access happening before one of the
+above lock-release function on any given CPU will be seen by all
+CPUs as happening before any access happening after a later one
+of the above lock-acquisition functions executing on that same CPU,
+even if the lock-release and lock-acquisition functions are operating
+on different ``rcu_node`` structures.
+Tree RCU uses these two ordering guarantees to form an ordering
+network among all CPUs that were in any way involved in the grace
+period, including any CPUs that came online or went offline during
+the grace period in question.
+
+The following litmus test exhibits the ordering effects of these
+lock-acquisition and lock-release functions::
+
+    1 int x, y, z;
+    2
+    3 void task0(void)
+    4 {
+    5   raw_spin_lock_rcu_node(rnp);
+    6   WRITE_ONCE(x, 1);
+    7   r1 = READ_ONCE(y);
+    8   raw_spin_unlock_rcu_node(rnp);
+    9 }
+   10
+   11 void task1(void)
+   12 {
+   13   raw_spin_lock_rcu_node(rnp);
+   14   WRITE_ONCE(y, 1);
+   15   r2 = READ_ONCE(z);
+   16   raw_spin_unlock_rcu_node(rnp);
+   17 }
+   18
+   19 void task2(void)
+   20 {
+   21   WRITE_ONCE(z, 1);
+   22   smp_mb();
+   23   r3 = READ_ONCE(x);
+   24 }
+   25
+   26 WARN_ON(r1 == 0 && r2 == 0 && r3 == 0);
+
+The ``WARN_ON()`` is evaluated at "the end of time",
+after all changes have propagated throughout the system.
+Without the ``smp_mb__after_unlock_lock()`` provided by the
+acquisition functions, this ``WARN_ON()`` could trigger, for example
+on PowerPC.
+The ``smp_mb__after_unlock_lock()`` invocations prevent this
+``WARN_ON()`` from triggering.
+

+| **Quick Quiz**:                                                       |
++-----------------------------------------------------------------------+
+| But the chain of rcu_node-structure lock acquisitions guarantees      |
+| that new readers will see all of the updater's pre-grace-period       |
+| accesses and also guarantees that the updater's post-grace-period     |
+| accesses will see all of the old reader's accesses.  So why do we     |
+| need all of those calls to smp_mb__after_unlock_lock()?               |
++-----------------------------------------------------------------------+
+| **Answer**:                                                           |
++-----------------------------------------------------------------------+
+| Because we must provide ordering for RCU's polling grace-period       |
+| primitives, for example, get_state_synchronize_rcu() and              |
+| poll_state_synchronize_rcu().  Consider this code::                   |
+|                                                                       |
+|  CPU 0                                     CPU 1                      |
+|  ----                                      ----                       |
+|  WRITE_ONCE(X, 1)                          WRITE_ONCE(Y, 1)           |
+|  g = get_state_synchronize_rcu()           smp_mb()                   |
+|  while (!poll_state_synchronize_rcu(g))    r1 = READ_ONCE(X)          |
+|          continue;                                                    |
+|  r0 = READ_ONCE(Y)                                                    |
+|                                                                       |
+| RCU guarantees that the outcome r0 == 0 && r1 == 0 will not           |
+| happen, even if CPU 1 is in an RCU extended quiescent state           |
+| (idle or offline) and thus won't interact directly with the RCU       |
+| core processing at all.                                               |
++-----------------------------------------------------------------------+
+
+This approach must be extended to include idle CPUs, which need
+RCU's grace-period memory ordering guarantee to extend to any
+RCU read-side critical sections preceding and following the current
+idle sojourn.
+This case is handled by calls to the strongly ordered
+``atomic_add_return()`` read-modify-write atomic operation that
+is invoked within ``rcu_dynticks_eqs_enter()`` at idle-entry
+time and within ``rcu_dynticks_eqs_exit()`` at idle-exit time.
+The grace-period kthread invokes ``rcu_dynticks_snap()`` and
+``rcu_dynticks_in_eqs_since()`` (both of which invoke
+an ``atomic_add_return()`` of zero) to detect idle CPUs.
+
++-----------------------------------------------------------------------+
+| **Quick Quiz**:                                                       |
++-----------------------------------------------------------------------+
+| But what about CPUs that remain offline for the entire grace period?  |
++-----------------------------------------------------------------------+
+| **Answer**:                                                           |
++-----------------------------------------------------------------------+
+| Such CPUs will be offline at the beginning of the grace period, so    |
+| the grace period won't expect quiescent states from them. Races       |
+| between grace-period start and CPU-hotplug operations are mediated    |
+| by the CPU's leaf ``rcu_node`` structure's ``->lock`` as described    |
+| above.                                                                |
++-----------------------------------------------------------------------+
+
+The approach must be extended to handle one final case, that of waking a
+task blocked in ``synchronize_rcu()``. This task might be affined to
+a CPU that is not yet aware that the grace period has ended, and thus
+might not yet be subject to the grace period's memory ordering.
+Therefore, there is an ``smp_mb()`` after the return from
+``wait_for_completion()`` in the ``synchronize_rcu()`` code path.
+
++-----------------------------------------------------------------------+
+| **Quick Quiz**:                                                       |
++-----------------------------------------------------------------------+
+| What? Where??? I don't see any ``smp_mb()`` after the return from     |
+| ``wait_for_completion()``!!!                                          |
++-----------------------------------------------------------------------+
+| **Answer**:                                                           |
++-----------------------------------------------------------------------+
+| That would be because I spotted the need for that ``smp_mb()`` during |
+| the creation of this documentation, and it is therefore unlikely to   |
+| hit mainline before v4.14. Kudos to Lance Roy, Will Deacon, Peter     |
+| Zijlstra, and Jonathan Cameron for asking questions that sensitized   |
+| me to the rather elaborate sequence of events that demonstrate the    |
+| need for this memory barrier.                                         |
++-----------------------------------------------------------------------+
+
+Tree RCU's grace--period memory-ordering guarantees rely most heavily on
+the ``rcu_node`` structure's ``->lock`` field, so much so that it is
+necessary to abbreviate this pattern in the diagrams in the next
+section. For example, consider the ``rcu_prepare_for_idle()`` function
+shown below, which is one of several functions that enforce ordering of
+newly arrived RCU callbacks against future grace periods:
+
+::
+
+    1 static void rcu_prepare_for_idle(void)
+    2 {
+    3   bool needwake;
+    4   struct rcu_data *rdp = this_cpu_ptr(&rcu_data);
+    5   struct rcu_node *rnp;
+    6   int tne;
+    7
+    8   lockdep_assert_irqs_disabled();
+    9   if (rcu_rdp_is_offloaded(rdp))
+   10     return;
+   11
+   12   /* Handle nohz enablement switches conservatively. */
+   13   tne = READ_ONCE(tick_nohz_active);
+   14   if (tne != rdp->tick_nohz_enabled_snap) {
+   15     if (!rcu_segcblist_empty(&rdp->cblist))
+   16       invoke_rcu_core(); /* force nohz to see update. */
+   17     rdp->tick_nohz_enabled_snap = tne;
+   18     return;
+   19	}
+   20   if (!tne)
+   21     return;
+   22
+   23   /*
+   24    * If we have not yet accelerated this jiffy, accelerate all
+   25    * callbacks on this CPU.
+   26   */
+   27   if (rdp->last_accelerate == jiffies)
+   28     return;
+   29   rdp->last_accelerate = jiffies;
+   30   if (rcu_segcblist_pend_cbs(&rdp->cblist)) {
+   31     rnp = rdp->mynode;
+   32     raw_spin_lock_rcu_node(rnp); /* irqs already disabled. */
+   33     needwake = rcu_accelerate_cbs(rnp, rdp);
+   34     raw_spin_unlock_rcu_node(rnp); /* irqs remain disabled. */
+   35     if (needwake)
+   36       rcu_gp_kthread_wake();
+   37   }
+   38 }
+
+But the only part of ``rcu_prepare_for_idle()`` that really matters for
+this discussion are lines 32–34. We will therefore abbreviate this
+function as follows:
+
+.. kernel-figure:: rcu_node-lock.svg
+
+The box represents the ``rcu_node`` structure's ``->lock`` critical
+section, with the double line on top representing the additional
+``smp_mb__after_unlock_lock()``.
+
+Tree RCU Grace Period Memory Ordering Components
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Tree RCU's grace-period memory-ordering guarantee is provided by a
+number of RCU components:
+
+#. `Callback Registry`_
+#. `Grace-Period Initialization`_
+#. `Self-Reported Quiescent States`_
+#. `Dynamic Tick Interface`_
+#. `CPU-Hotplug Interface`_
+#. `Forcing Quiescent States`_
+#. `Grace-Period Cleanup`_
+#. `Callback Invocation`_
+
+Each of the following section looks at the corresponding component in
+detail.
+
+Callback Registry
+^^^^^^^^^^^^^^^^^
+
+If RCU's grace-period guarantee is to mean anything at all, any access
+that happens before a given invocation of ``call_rcu()`` must also
+happen before the corresponding grace period. The implementation of this
+portion of RCU's grace period guarantee is shown in the following
+figure:
+
+.. kernel-figure:: TreeRCU-callback-registry.svg
+
+Because ``call_rcu()`` normally acts only on CPU-local state, it
+provides no ordering guarantees, either for itself or for phase one of
+the update (which again will usually be removal of an element from an
+RCU-protected data structure). It simply enqueues the ``rcu_head``
+structure on a per-CPU list, which cannot become associated with a grace
+period until a later call to ``rcu_accelerate_cbs()``, as shown in the
+diagram above.
+
+One set of code paths shown on the left invokes ``rcu_accelerate_cbs()``
+via ``note_gp_changes()``, either directly from ``call_rcu()`` (if the
+current CPU is inundated with queued ``rcu_head`` structures) or more
+likely from an ``RCU_SOFTIRQ`` handler. Another code path in the middle
+is taken only in kernels built with ``CONFIG_RCU_FAST_NO_HZ=y``, which
+invokes ``rcu_accelerate_cbs()`` via ``rcu_prepare_for_idle()``. The
+final code path on the right is taken only in kernels built with
+``CONFIG_HOTPLUG_CPU=y``, which invokes ``rcu_accelerate_cbs()`` via
+``rcu_advance_cbs()``, ``rcu_migrate_callbacks``,
+``rcutree_migrate_callbacks()``, and ``takedown_cpu()``, which in turn
+is invoked on a surviving CPU after the outgoing CPU has been completely
+offlined.
+
+There are a few other code paths within grace-period processing that
+opportunistically invoke ``rcu_accelerate_cbs()``. However, either way,
+all of the CPU's recently queued ``rcu_head`` structures are associated
+with a future grace-period number under the protection of the CPU's lead
+``rcu_node`` structure's ``->lock``. In all cases, there is full
+ordering against any prior critical section for that same ``rcu_node``
+structure's ``->lock``, and also full ordering against any of the
+current task's or CPU's prior critical sections for any ``rcu_node``
+structure's ``->lock``.
+
+The next section will show how this ordering ensures that any accesses
+prior to the ``call_rcu()`` (particularly including phase one of the
+update) happen before the start of the corresponding grace period.
+

++-----------------------------------------------------------------------+
+| But what about ``synchronize_rcu()``?                                 |
++-----------------------------------------------------------------------+
+| **Answer**:                                                           |
++-----------------------------------------------------------------------+
+| The ``synchronize_rcu()`` passes ``call_rcu()`` to ``wait_rcu_gp()``, |
+| which invokes it. So either way, it eventually comes down to          |
+| ``call_rcu()``.                                                       |
++-----------------------------------------------------------------------+
+
+Grace-Period Initialization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Grace-period initialization is carried out by the grace-period kernel
+thread, which makes several passes over the ``rcu_node`` tree within the
+``rcu_gp_init()`` function. This means that showing the full flow of
+ordering through the grace-period computation will require duplicating
+this tree. If you find this confusing, please note that the state of the
+``rcu_node`` changes over time, just like Heraclitus's river. However,
+to keep the ``rcu_node`` river tractable, the grace-period kernel
+thread's traversals are presented in multiple parts, starting in this
+section with the various phases of grace-period initialization.
+
+The first ordering-related grace-period initialization action is to
+advance the ``rcu_state`` structure's ``->gp_seq`` grace-period-number
+counter, as shown below:
+
+.. kernel-figure:: TreeRCU-gp-init-1.svg
+
+The actual increment is carried out using ``smp_store_release()``, which
+helps reject false-positive RCU CPU stall detection. Note that only the
+root ``rcu_node`` structure is touched.
+
+The first pass through the ``rcu_node`` tree updates bitmasks based on
+CPUs having come online or gone offline since the start of the previous
+grace period. In the common case where the number of online CPUs for
+this ``rcu_node`` structure has not transitioned to or from zero, this
+pass will scan only the leaf ``rcu_node`` structures. However, if the
+number of online CPUs for a given leaf ``rcu_node`` structure has
+transitioned from zero, ``rcu_init_new_rnp()`` will be invoked for the
+first incoming CPU. Similarly, if the number of online CPUs for a given
+leaf ``rcu_node`` structure has transitioned to zero,
+``rcu_cleanup_dead_rnp()`` will be invoked for the last outgoing CPU.
+The diagram below shows the path of ordering if the leftmost
+``rcu_node`` structure onlines its first CPU and if the next
+``rcu_node`` structure has no online CPUs (or, alternatively if the
+leftmost ``rcu_node`` structure offlines its last CPU and if the next
+``rcu_node`` structure has no online CPUs).
+
+.. kernel-figure:: TreeRCU-gp-init-2.svg
+
+The final ``rcu_gp_init()`` pass through the ``rcu_node`` tree traverses
+breadth-first, setting each ``rcu_node`` structure's ``->gp_seq`` field
+to the newly advanced value from the ``rcu_state`` structure, as shown
+in the following diagram.
+
+.. kernel-figure:: TreeRCU-gp-init-3.svg
+
+This change will also cause each CPU's next call to
+``__note_gp_changes()`` to notice that a new grace period has started,
+as described in the next section. But because the grace-period kthread
+started the grace period at the root (with the advancing of the
+``rcu_state`` structure's ``->gp_seq`` field) before setting each leaf
+``rcu_node`` structure's ``->gp_seq`` field, each CPU's observation of
+the start of the grace period will happen after the actual start of the
+grace period.
+
++-----------------------------------------------------------------------+

++-----------------------------------------------------------------------+
+| But what about the CPU that started the grace period? Why wouldn't it |
+| see the start of the grace period right when it started that grace    |
+| period?                                                               |
++-----------------------------------------------------------------------+
+| **Answer**:                                                           |
++-----------------------------------------------------------------------+
+| In some deep philosophical and overly anthromorphized sense, yes, the |
+| CPU starting the grace period is immediately aware of having done so. |
+| However, if we instead assume that RCU is not self-aware, then even   |
+| the CPU starting the grace period does not really become aware of the |
+| start of this grace period until its first call to                    |
+| ``__note_gp_changes()``. On the other hand, this CPU potentially gets |
+| early notification because it invokes ``__note_gp_changes()`` during  |
+| its last ``rcu_gp_init()`` pass through its leaf ``rcu_node``         |
+| structure.                                                            |
++-----------------------------------------------------------------------+
+
+Self-Reported Quiescent States
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When all entities that might block the grace period have reported
+quiescent states (or as described in a later section, had quiescent
+states reported on their behalf), the grace period can end. Online
+non-idle CPUs report their own quiescent states, as shown in the
+following diagram:
+
+.. kernel-figure:: TreeRCU-qs.svg
+
+This is for the last CPU to report a quiescent state, which signals the
+end of the grace period. Earlier quiescent states would push up the
+``rcu_node`` tree only until they encountered an ``rcu_node`` structure
+that is waiting for additional quiescent states. However, ordering is
+nevertheless preserved because some later quiescent state will acquire
+that ``rcu_node`` structure's ``->lock``.
+
+Any number of events can lead up to a CPU invoking ``note_gp_changes``
+(or alternatively, directly invoking ``__note_gp_changes()``), at which
+point that CPU will notice the start of a new grace period while holding
+its leaf ``rcu_node`` lock. Therefore, all execution shown in this
+diagram happens after the start of the grace period. In addition, this
+CPU will consider any RCU read-side critical section that started before
+the invocation of ``__note_gp_changes()`` to have started before the
+grace period, and thus a critical section that the grace period must
+wait on.
+
++-----------------------------------------------------------------------+
+| **Quick Quiz**:                                                       |
++-----------------------------------------------------------------------+
+| But a RCU read-side critical section might have started after the     |
+| beginning of the grace period (the advancing of ``->gp_seq`` from     |
+| earlier), so why should the grace period wait on such a critical      |
+| section?                                                              |
++-----------------------------------------------------------------------+
+| **Answer**:                                                           |
++-----------------------------------------------------------------------+
+| It is indeed not necessary for the grace period to wait on such a     |
+| critical section. However, it is permissible to wait on it. And it is |
+| furthermore important to wait on it, as this lazy approach is far     |
+| more scalable than a “big bang” all-at-once grace-period start could  |
+| possibly be.                                                          |
++-----------------------------------------------------------------------+
+
+If the CPU does a context switch, a quiescent state will be noted by
+``rcu_note_context_switch()`` on the left. On the other hand, if the CPU
+takes a scheduler-clock interrupt while executing in usermode, a
+quiescent state will be noted by ``rcu_sched_clock_irq()`` on the right.
+Either way, the passage through a quiescent state will be noted in a
+per-CPU variable.
+
+The next time an ``RCU_SOFTIRQ`` handler executes on this CPU (for
+example, after the next scheduler-clock interrupt), ``rcu_core()`` will
+invoke ``rcu_check_quiescent_state()``, which will notice the recorded
+quiescent state, and invoke ``rcu_report_qs_rdp()``. If
+``rcu_report_qs_rdp()`` verifies that the quiescent state really does
+apply to the current grace period, it invokes ``rcu_report_rnp()`` which
+traverses up the ``rcu_node`` tree as shown at the bottom of the
+diagram, clearing bits from each ``rcu_node`` structure's ``->qsmask``
+field, and propagating up the tree when the result is zero.
+
+Note that traversal passes upwards out of a given ``rcu_node`` structure
+only if the current CPU is reporting the last quiescent state for the
+subtree headed by that ``rcu_node`` structure. A key point is that if a
+CPU's traversal stops at a given ``rcu_node`` structure, then there will
+be a later traversal by another CPU (or perhaps the same one) that
+proceeds upwards from that point, and the ``rcu_node`` ``->lock``
+guarantees that the first CPU's quiescent state happens before the
+remainder of the second CPU's traversal. Applying this line of thought
+repeatedly shows that all CPUs' quiescent states happen before the last
+CPU traverses through the root ``rcu_node`` structure, the “last CPU”
+being the one that clears the last bit in the root ``rcu_node``
+structure's ``->qsmask`` field.
+
+Dynamic Tick Interface
+^^^^^^^^^^^^^^^^^^^^^^
+
+Due to energy-efficiency considerations, RCU is forbidden from
+disturbing idle CPUs. CPUs are therefore required to notify RCU when
+entering or leaving idle state, which they do via fully ordered
+value-returning atomic operations on a per-CPU variable. The ordering
+effects are as shown below:
+
+.. kernel-figure:: TreeRCU-dyntick.svg
+
+The RCU grace-period kernel thread samples the per-CPU idleness variable
+while holding the corresponding CPU's leaf ``rcu_node`` structure's
+``->lock``. This means that any RCU read-side critical sections that
+precede the idle period (the oval near the top of the diagram above)
+will happen before the end of the current grace period. Similarly, the
+beginning of the current grace period will happen before any RCU
+read-side critical sections that follow the idle period (the oval near
+the bottom of the diagram above).
+
+Plumbing this into the full grace-period execution is described
+`below <Forcing Quiescent States_>`__.
+
+CPU-Hotplug Interface
+^^^^^^^^^^^^^^^^^^^^^
+
+RCU is also forbidden from disturbing offline CPUs, which might well be
+powered off and removed from the system completely. CPUs are therefore
+required to notify RCU of their comings and goings as part of the
+corresponding CPU hotplug operations. The ordering effects are shown
+below:
+
+.. kernel-figure:: TreeRCU-hotplug.svg
+
+Because CPU hotplug operations are much less frequent than idle
+transitions, they are heavier weight, and thus acquire the CPU's leaf
+``rcu_node`` structure's ``->lock`` and update this structure's
+``->qsmaskinitnext``. The RCU grace-period kernel thread samples this
+mask to detect CPUs having gone offline since the beginning of this
+grace period.
+
+Plumbing this into the full grace-period execution is described
+`below <Forcing Quiescent States_>`__.
+
+Forcing Quiescent States
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+As noted above, idle and offline CPUs cannot report their own quiescent
+states, and therefore the grace-period kernel thread must do the
+reporting on their behalf. This process is called “forcing quiescent
+states”, it is repeated every few jiffies, and its ordering effects are
+shown below:
+
+.. kernel-figure:: TreeRCU-gp-fqs.svg
+
+Each pass of quiescent state forcing is guaranteed to traverse the leaf
+``rcu_node`` structures, and if there are no new quiescent states due to
+recently idled and/or offlined CPUs, then only the leaves are traversed.
+However, if there is a newly offlined CPU as illustrated on the left or
+a newly idled CPU as illustrated on the right, the corresponding
+quiescent state will be driven up towards the root. As with
+self-reported quiescent states, the upwards driving stops once it
+reaches an ``rcu_node`` structure that has quiescent states outstanding
+from other CPUs.

++-----------------------------------------------------------------------+
+| The leftmost drive to root stopped before it reached the root         |
+| ``rcu_node`` structure, which means that there are still CPUs         |
+| subordinate to that structure on which the current grace period is    |
+| waiting. Given that, how is it possible that the rightmost drive to   |
+| root ended the grace period?                                          |

++-----------------------------------------------------------------------+
+| Good analysis! It is in fact impossible in the absence of bugs in     |
+| RCU. But this diagram is complex enough as it is, so simplicity       |
+| overrode accuracy. You can think of it as poetic license, or you can  |
+| think of it as misdirection that is resolved in the                   |
+| `stitched-together diagram <Putting It All Together_>`__.             |

+
+Grace-Period Cleanup
+^^^^^^^^^^^^^^^^^^^^
+
+Grace-period cleanup first scans the ``rcu_node`` tree breadth-first
+advancing all the ``->gp_seq`` fields, then it advances the
+``rcu_state`` structure's ``->gp_seq`` field. The ordering effects are
+shown below:
+
+.. kernel-figure:: TreeRCU-gp-cleanup.svg
+
+As indicated by the oval at the bottom of the diagram, once grace-period
+cleanup is complete, the next grace period can begin.
+
++-----------------------------------------------------------------------+
+| **Quick Quiz**:                                                       |
++-----------------------------------------------------------------------+
+| But when precisely does the grace period end?                         |
++-----------------------------------------------------------------------+
+| **Answer**:                                                           |
++-----------------------------------------------------------------------+
+| There is no useful single point at which the grace period can be said |
+| to end. The earliest reasonable candidate is as soon as the last CPU  |
+| has reported its quiescent state, but it may be some milliseconds     |
+| before RCU becomes aware of this. The latest reasonable candidate is  |
+| once the ``rcu_state`` structure's ``->gp_seq`` field has been        |
+| updated, but it is quite possible that some CPUs have already         |
+| completed phase two of their updates by that time. In short, if you   |
+| are going to work with RCU, you need to learn to embrace uncertainty. |
++-----------------------------------------------------------------------+
+
+Callback Invocation
+^^^^^^^^^^^^^^^^^^^
+
+Once a given CPU's leaf ``rcu_node`` structure's ``->gp_seq`` field has
+been updated, that CPU can begin invoking its RCU callbacks that were
+waiting for this grace period to end. These callbacks are identified by
+``rcu_advance_cbs()``, which is usually invoked by
+``__note_gp_changes()``. As shown in the diagram below, this invocation
+can be triggered by the scheduling-clock interrupt
+(``rcu_sched_clock_irq()`` on the left) or by idle entry
+(``rcu_cleanup_after_idle()`` on the right, but only for kernels build
+with ``CONFIG_RCU_FAST_NO_HZ=y``). Either way, ``RCU_SOFTIRQ`` is
+raised, which results in ``rcu_do_batch()`` invoking the callbacks,
+which in turn allows those callbacks to carry out (either directly or
+indirectly via wakeup) the needed phase-two processing for each update.
+
+.. kernel-figure:: TreeRCU-callback-invocation.svg
+
+Please note that callback invocation can also be prompted by any number
+of corner-case code paths, for example, when a CPU notes that it has
+excessive numbers of callbacks queued. In all cases, the CPU acquires
+its leaf ``rcu_node`` structure's ``->lock`` before invoking callbacks,
+which preserves the required ordering against the newly completed grace
+period.
+
+However, if the callback function communicates to other CPUs, for
+example, doing a wakeup, then it is that function's responsibility to
+maintain ordering. For example, if the callback function wakes up a task
+that runs on some other CPU, proper ordering must in place in both the
+callback function and the task being awakened. To see why this is
+important, consider the top half of the `grace-period
+cleanup`_ diagram. The callback might be
+running on a CPU corresponding to the leftmost leaf ``rcu_node``
+structure, and awaken a task that is to run on a CPU corresponding to
+the rightmost leaf ``rcu_node`` structure, and the grace-period kernel
+thread might not yet have reached the rightmost leaf. In this case, the
+grace period's memory ordering might not yet have reached that CPU, so
+again the callback function and the awakened task must supply proper
+ordering.
