H A Dtmpfs.rst76 mpol=default 采用进程分配策略
78 mpol=prefer:Node 倾向从给定的节点分配
79 mpol=bind:NodeList 只允许从指定的链表分配
80 mpol=interleave 倾向于依次从每个节点分配
81 mpol=interleave:NodeList 依次从每个节点分配
82 mpol=local 优先本地节点分配内存
86 分隔符的十进制数来表示。例如，mpol=bind0-3,5,7,9-15
104 例如，mpol=bind=staticNodeList相当于MPOL_BIND|MPOL_F_STATIC_NODES的分配策略
106 请注意，如果内核不支持NUMA，那么使用mpol选项挂载tmpfs将会失败；nodelist指定不
108 revocery内核)，或者具有较少的节点在线，建议从自动模式中省略mpol选项挂载选项。

H A Dtmpfs.rst76 mpol=default 採用進程分配策略
78 mpol=prefer:Node 傾向從給定的節點分配
79 mpol=bind:NodeList 只允許從指定的鏈表分配
80 mpol=interleave 傾向於依次從每個節點分配
81 mpol=interleave:NodeList 依次從每個節點分配
82 mpol=local 優先本地節點分配內存
86 分隔符的十進制數來表示。例如，mpol=bind0-3,5,7,9-15
104 例如，mpol=bind=staticNodeList相當於MPOL_BIND|MPOL_F_STATIC_NODES的分配策略
106 請注意，如果內核不支持NUMA，那麼使用mpol選項掛載tmpfs將會失敗；nodelist指定不
108 revocery內核)，或者具有較少的節點在線，建議從自動模式中省略mpol選項掛載選項。
