From 7b2a2d4a18fffac3c4872021529b0657896db788 Mon Sep 17 00:00:00 2001 From: Mel Gorman Date: Fri, 19 Oct 2012 14:07:31 +0100 Subject: mm: migrate: Add a tracepoint for migrate_pages The pgmigrate_success and pgmigrate_fail vmstat counters tells the user about migration activity but not the type or the reason. This patch adds a tracepoint to identify the type of page migration and why the page is being migrated.
