Subject: [PATCH 1/2] mm/page_alloc: fix wrong initialization when sysctl_min_unmapped_ratio changes
Date: Tue, 9 Aug 2016 15:30:47 +0900 [thread overview]
Message-ID: <1470724248-26780-1-git-send-email-iamjoonsoo.kim@lge.com> (raw)
From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Before resetting min_unmapped_pages, we need to initialize
min_unmapped_pages rather than min_slab_pages.
Fixes: a5f5f91da6 (mm: convert zone_reclaim to node_reclaim)
