关于内存碎片，搜到几篇lwn的老文章，仅供参考&备忘。

Page migration

Sometimes processes must be moved, however, with the result that the local-allocation optimization can quickly become a pessimization instead. What would be nice, in such situations, would be the ability to move a process's memory when the process itself is shifted to a new node.
