Subject: [PATCH 3/7] mm/memblock: memblock_is_memory/reserved can be boolean
Date: Mon, 16 Nov 2015 14:51:22 +0800	[thread overview]
Message-ID: <1447656686-4851-4-git-send-email-baiyaowei@cmss.chinamobile.com> (raw)
In-Reply-To: <1447656686-4851-1-git-send-email-baiyaowei@cmss.chinamobile.com>

This patch makes memblock_is_memory/reserved return bool to improve
readability due to this particular function only using either
one or zero as its return value.

No functional change.
