Revision c1470b33bb6e18cddd361fef339ef225b8339fe7 authored by zhong jiang on 11 August 2016, 22:32:55 UTC, committed by Linus Torvalds on 11 August 2016, 23:58:13 UTC
When memory hotplug operates, free hugepages will be freed if the movable node is offline. Therefore, /proc/sys/vm/nr_hugepages will be incorrect. Fix it by reducing max_huge_pages when the node is offlined. n-horiguchi@ah.jp.nec.com said: : dissolve_free_huge_page intends to break a hugepage into buddy, and the : destination hugepage is supposed to be allocated from the pool of the : destination node, so the system-wide pool size is reduced. So adding : h->max_huge_pages-- makes sense to me.
