Subject: [PATCH 03/10] mm/page_alloc: use unsigned int for "order" in should_compact_retry()
Date: Fri, 26 Jul 2019 02:42:46 +0800	[thread overview]
Message-ID: <20190725184253.21160-4-lpf.vector@gmail.com> (raw)
In-Reply-To: <20190725184253.21160-1-lpf.vector@gmail.com>

Because "order" will never be negative in should_compact_retry(),
so just make "order" unsigned int.
