From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx> When running the --date option of trace-cmd record it loops through writing to the trace_marker and reading the timestamp from trace_pipe_raw. But it never closes the file descriptor it used to open trace_pipe_raw with. This prevents other parts of trace-cmd from working like writing "function" into current_tracer, because the trace_pipe_raw will hold a ref count and not let different tracers be set if that file is open.
