Subject: [PATCH] mm/vmscan: change return type of is_page_cache_freeable from int to bool
Date:   Tue, 28 Nov 2017 10:48:27 +0800
Message-Id: <1511837307-56494-1-git-send-email-jiang.biao2@zte.com.cn>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Using bool for the return type of is_page_cache_freeable() should be
more appropriate.
