函数名称：The cluster corresponding to page_nr will be used. The cluster will be* removed from free cluster list and its usage counter will be increased.
函数原型：static void inc_cluster_info_page(struct swap_info_struct *p, struct swap_cluster_info *cluster_info, unsigned long page_nr)
返回类型：void
参数：
| 类型 | 参数 | 名称 |
|---|---|---|
| struct swap_info_struct * | p | |
| struct swap_cluster_info * | cluster_info | |
| unsigned long | page_nr |
| 538 | idx等于page_nr除SWAPFILE_CLUSTER |
| 540 | 如果非cluster_info则返回 |
| 542 | 如果cluster_is_free( & cluster_info[idx])则alloc_cluster(p, idx) |
| 545 | VM_BUG_ON(cluster_count( & cluster_info[idx]) >= SWAPFILE_CLUSTER) |
| 546 | cluster_set_count( & cluster_info[idx], cluster_count( & cluster_info[idx]) + 1) |
