CPU's leaf <tt>rcu_node</tt> structure's +<tt>->completed</tt> 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 <tt>rcu_advance_cbs()</tt>, +which is usually invoked by <tt>__note_gp_changes()</tt>. +As shown in the diagram below, this invocation can be triggered by +the scheduling-clock interrupt (<tt>rcu_check_callbacks()</tt> on +the left) or by idle entry (<tt>rcu_cleanup_after_idle()</tt> on +the right, but only for kernels build with +<tt>CONFIG_RCU_FAST_NO_HZ=y</tt>). +Either way, <tt>RCU_SOFTIRQ</tt> is raised, which results in +<tt>rcu_do_batch()</tt> 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. + +</p><p><img src="TreeRCU-callback-invocation.svg" alt="TreeRCU-callback-invocation.svg" width="60%"> + +<p>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 <tt>rcu_node</tt> structure's +<tt>->lock</tt> before invoking callbacks, which preserves the +required ordering against the newly completed grace period. + +<p>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 +<a href="#Grace-Period Cleanup">grace-period cleanup</a> diagram. +The callback might be running on a CPU corresponding to the leftmost +leaf <tt>rcu_node</tt> structure, and awaken a task that is to run on +a CPU corresponding to the rightmost leaf <tt>rcu_node</tt> 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. + +<h3><a name="Putting It All Together">Putting It All Together</a></h3> + +<p>A stitched-together diagram is +<a
