Subject: [PATCH 3.19.y-ckt 34/54] mm: vmscan: reclaim highmem zone if buffer_heads is over limit
Date: Mon, 9 May 2016 17:04:53 -0700 [thread overview]
Message-ID: <1462838713-31343-35-git-send-email-kamal@canonical.com> (raw)
In-Reply-To: <1462838713-31343-1-git-send-email-kamal@canonical.com>
3.19.8-ckt21 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Minchan Kim <minchan@kernel.org>
commit 7bf52fb891b64b8d61caf0b82060adb9db761aec upstream.
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.
Fixes: 6b4f7799c6a5 ("mm: vmscan: invoke slab shrinkers from shrink_zone()")
