Subject[PATCH 1/2] mm/page_alloc: fix wrong initialization when sysctl_min_unmapped_ratio changes
Date
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)
