| * 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 bits 0 and 1 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(). |
