A Dmemory-hotplug.rst73 - status_change_nid_normal是当nodemask的N_NORMAL_MEMORY被设置/清除时设置节
74 点id，如果是-1，则nodemask状态不改变。
76 - status_change_nid是当nodemask的N_MEMORY被（将）设置/清除时设置的节点id。这
78 存。如果这个值为-1，那么nodemask的状态就不会改变。
A Dprintk-formats.rst533 位图及其衍生物，如cpumask和nodemask

A Dnuma_memory_policy.rst215 is always preferred by passing an empty nodemask with this
216 mode. If an empty nodemask is passed, the policy cannot use
249 a memory pressure on all nodes in the nodemask, the allocation

285 This flag specifies that the nodemask passed
293 nodes, the node (Preferred) or nodemask (Bind, Interleave) is
296 set of allowed nodes upon successive rebinds: a nodemask of
301 the user's passed nodemask are relative to the set of allowed
