This case is handled by calls to the strongly ordered

is invoked within ``rcu_dynticks_eqs_enter()`` at idle-entry

The grace-period kthread invokes first ``ct_rcu_watching_cpu_acquire()``
(preceded by a full memory barrier) and ``rcu_watching_snap_stopped_since()``
(both of which rely on acquire semantics) to detect idle CPUs.
