Steven Rostedt (Red Hat) f487426104 tracing: Break out of tracing_wait_pipe() before wait_pipe() is called ... When reading from trace_pipe, if tracing is off but nothing was read it should block. If something is read and tracing is off, then EOF is returned. If tracing is on and there's nothing to read, it will block. But because the check of whether tracing is off and something was read is done after the block on the pipe, it is hit or miss if the EOF is returned or not leading to inconsistent behavior.
