208 * The struct is aligned to size of pointer. On most architectures it happens
209 * naturally due ABI requirements, but some architectures (like CRIS) have
210 * weird ABI and we need to ask it explicitly.
212 * The alignment is required to guarantee that bits 0 and 1 of @next will be
213 * clear under normal conditions -- as long as we use call_rcu(),
214 * call_rcu_bh(), call_rcu_sched(), or call_srcu() to queue callback.
216 * This guarantee is important for few reasons:
217 * - future call_rcu_lazy() will make use of lower bits in the pointer;
218 * - the structure shares storage spacer in struct page with @compound_head,
219 * which encode PageTail() in bit 0. The guarantee is needed to avoid
220 * false-positive PageTail().
