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 <masbock@linux.vnet.ibm.com> Acked-by: Steven Rostedt <rostedt@goodmis.org> Cc: Ingo Molnar <mingo@redhat.com> Acked-by: Mel Gorman <mgorman@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
