From 7bf52fb891b64b8d61caf0b82060adb9db761aec Mon Sep 17 00:00:00 2001 From: Minchan Kim Date: Thu, 28 Apr 2016 16:18:38 -0700 Subject: mm: vmscan: reclaim highmem zone if buffer_heads is over limit We have been reclaimed highmem zone if buffer_heads is over limit but commit 6b4f7799c6a5 ("mm: vmscan: invoke slab shrinkers from shrink_zone()") changed the behavior so it doesn't reclaim highmem zone although buffer_heads is over the limit. This patch restores the logic.
