From 0e88460da6ab7bb6a7ef83675412ed5b6315d741 Mon Sep 17 00:00:00 2001 From: Mel Gorman Date: Mon, 28 Apr 2008 02:12:14 -0700 Subject: mm: introduce node_zonelist() for accessing the zonelist for a GFP mask Introduce a node_zonelist() helper function. It is used to lookup the appropriate zonelist given a node and a GFP mask. The patch on its own is a cleanup but it helps clarify parts of the two-zonelist-per-node patchset. If necessary, it can be merged with the next patch in this set without problems.
