From 4a262d265878477a46c842e47d1c2b5ce6f66477 Mon Sep 17 00:00:00 2001 From: Max Asbock Date: Wed, 6 Aug 2014 16:06:21 -0700 Subject: [PATCH] mm tracing: tell mm_migrate_pages event about numa_misplaced The mm_migrate_pages trace event reports a reason for the migration, typically as a symbolic string. The exception is the reason MR_NUMA_MISPLACED for which it just displays the numeric value: mm_migrate_pages: nr_succeeded=1 nr_failed=0 mode=MIGRATE_ASYNC reason=0x5 This patch makes the output consistent by introducing a string value for MR_NUMA_MISPLACED. The event is then reported as: mm_migrate_pages: nr_succeeded=1 nr_failed=0 mode=MIGRATE_ASYNC reason=numa_misplaced Signed-off-by: Max Asbock Acked-by: Steven Rostedt Cc: Ingo Molnar Acked-by: Mel Gorman Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/trace/events/migrate.h | 1 + 1 file changed, 1 insertion(+) diff --git a/include/trace/events/migrate.h b/include/trace/events/migrate.h index 4e4f2f8b1ac2..dd2b5467d905 100644 --- a/include/trace/events/migrate.h +++ b/include/trace/events/migrate.h @@ -17,6 +17,7 @@ {MR_MEMORY_HOTPLUG, "memory_hotplug"}, \ {MR_SYSCALL, "syscall_or_cpuset"}, \ {MR_MEMPOLICY_MBIND, "mempolicy_mbind"}, \ + {MR_NUMA_MISPLACED, "numa_misplaced"}, \ {MR_CMA, "cma"} TRACE_EVENT(mm_migrate_pages, -- GitLab
