         Note that, rcu_assign_pointer() and rcu_dereference() relate to
         SRCU just as they do to other forms of RCU.

+15.     The whole point of call_rcu(), synchronize_rcu(), and friends
+        is to wait until all pre-existing readers have finished before
+        carrying out some otherwise-destructive operation.  It is
+        therefore critically important to -first- remove any path
+        that readers can follow that could be affected by the
+        destructive operation, and -only- -then- invoke call_rcu(),
+        synchronize_rcu(), or friends.
+
+        Because these primitives only wait for pre-existing readers,
+        it is the caller's responsibility to guarantee safety to
+        any subsequent readers.
