A Dhugetlbfs_reserv.rst415 * 当cpuset被配置时，它打破了严格的hugetlb页面预留，因为计数是在一个全局变量上完
416 * 成的。在有cpuset的情况下，这样的预留完全是垃圾，因为预留没有根据当前cpuset的
417 * 页面可用性来检查。在任务所在的cpuset中缺乏空闲的htlb页面时，应用程序仍然有可能
418 * 被内核OOM'ed。试图用cpuset来执行严格的计数几乎是不可能的（或者说太难看了），因
419 * 为cpuset太不稳定了，任务或内存节点可以在cpuset之间动态移动。与cpuset共享
421 * 页的可用性，作为一种最好的尝试，希望能将cpuset改变语义的影响降到最低。
