From 7f0f24967b0349798803260b2e4bf347cffa1990 Mon Sep 17 00:00:00 2001 From: Mel Gorman Date: Thu, 13 Jan 2011 15:45:58 -0800 Subject: [PATCH] mm: migration: cleanup migrate_pages API by matching types for offlining and sync With the introduction of the boolean sync parameter, the API looks a little inconsistent as offlining is still an int. Convert offlining to a bool for the sake of being tidy.
