Subject: [PATCH 07/22] mm: page allocator: Do not lookup the pageblock migratetype during allocation
Date: Wed, 8 May 2013 17:02:52 +0100 [thread overview]
Message-ID: <1368028987-8369-8-git-send-email-mgorman@suse.de> (raw)
In-Reply-To: <1368028987-8369-1-git-send-email-mgorman@suse.de>
The pageblock migrate type is checked during allocation in case it's CMA
but using get_freepage_migratetype() should be sufficient as the
magazines would have been drained prior to a CMA allocation attempt.
