From ee64fc9354e515a79c7232cfde65c88ec627308b Mon Sep 17 00:00:00 2001 From: Mel Gorman Date: Thu, 13 Jan 2011 15:45:55 -0800 Subject: mm: vmscan: convert lumpy_mode into a bitmask Currently lumpy_mode is an enum and determines if lumpy reclaim is off, syncronous or asyncronous. In preparation for using compaction instead of lumpy reclaim, this patch converts the flags into a bitmap.
