[PATCH] trace-cmd: Fix left open file descriptor in recording of date

[Steven Rostedt <rostedt@goodmis.org>]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

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.

Fixes: e09a5db1a ("trace-cmd: Add trace-cmd record --date option")
