Dmemory-hotplug.rst74 - status_change_nid_normal是当nodemask的N_NORMAL_MEMORY被设置/清除时设置节
75 点id，如果是-1，则nodemask状态不改变。
77 - status_change_nid_high是当nodemask的N_HIGH_MEMORY被设置/清除时设置的节点
78 id，如果这个值为-1，那么nodemask状态不会改变。
80 - status_change_nid是当nodemask的N_MEMORY被（将）设置/清除时设置的节点id。这
82 存。如果这个值为-1，那么nodemask的状态就不会改变。
Dprintk-formats.rst532 位图及其衍生物，如cpumask和nodemask
540 对于打印位图（bitmap）及其派生的cpumask和nodemask，%*pb输出以字段宽度为位数的位图，
544 nodemask_pr_args()来方便打印cpumask和nodemask。
