Subject: [PATCH 07/14] Move definition for LRU isolation modes to a header
Date: Tue, 30 Mar 2010 10:14:42 +0100 [thread overview]
Message-ID: <1269940489-5776-8-git-send-email-mel@csn.ul.ie> (raw)
In-Reply-To: <1269940489-5776-1-git-send-email-mel@csn.ul.ie>
Currently, vmscan.c defines the isolation modes for
__isolate_lru_page(). Memory compaction needs access to these modes for
isolating pages for migration. This patch exports them.
Signed-off-by: Mel Gorman <mel@csn.ul.ie>
