Steven Rostedt (Google) 9d52727f80 tracing: Have tracing_snapshot_instance_cond() write errors to the appropriate instance ... If a trace instance has a failure with its snapshot code, the error message is to be written to that instance's buffer. But currently, the message is written to the top level buffer. Worse yet, it may also disable the top level buffer and not the instance that had the issue.
