 * struct callback_head - callback structure for use with RCU and task_work

 * The struct is aligned to size of pointer. On most architectures it happens
 * naturally due ABI requirements, but some architectures (like CRIS) have
 * 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(),
 * call_rcu_bh(), call_rcu_sched(), or call_srcu() to queue 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 spacer in struct page with @compound_head,
 *    which encode PageTail() in bit 0. The guarantee is needed to avoid
 *    false-positive PageTail().
