Looking at https://bugzilla.kernel.org/show_bug.cgi?id=216577 and analyzing
the fix, I found a bunch of other issues with trace-cmd stream.

This series is to address them.

Steven Rostedt (Google) (10):
  trace-cmd library: Set recorder to nonblock when finished
  trace-cmd stream: Do not block when stopping threads
  trace-cmd stream: Add a flush signal to kick the output
  trace-cmd stream: Do one last flush when finished
  trace-cmd library: Fix read_data() with error from tracefs_cpu_read()
  trace-cmd: Have trace_stream_read() use poll()
  trace-cmd stream: Set default sleep time to half a second
  trace-cmd library: Return the result of tracefs_cpu_stop()
  trace-cmd record: Set sleep_time to zero at end of recording
  trace-cmd record: Keep stopping the recording when finished
