+ * weird ABI and we need to ask it explicitly.
+ *
+ * The alignment is required to guarantee that bit 0 of @next will be
+ * clear under normal conditions -- as long as we use call_rcu() or
+ * call_srcu() to queue the callback.
+ *
+ * This guarantee is important for few reasons:
+ *  - future call_rcu_lazy() will make use of lower bits in the pointer;
+ *  - the structure shares storage space in struct page with @compound_head,
+ *    which encode PageTail() in bit 0. The guarantee is needed to avoid
+ *    false-positive PageTail().
