* 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().
