It's rather strange to be checking the debugfs MAGIC number for the tracing directory. A system admin may want to have a custom set of events to trace and it should be allowed to let the admin make a temp file (even for tracing virtual boxes, this is useful). Also with the coming tracefs, the files may not even be under debugfs, so checking the debugfs MAGIC number is pointless.
