Currently btt -B option for bno_plot.py writes data when trace action is "D-issued". But device mapper blktrace data do not contain "D" events, so bno_plot.py can not plot block IO to dm-target. This patche changes the caller of bno_dump_add which collects data for bno_plot.py from handle_issue() to handle_complete(). Device mapper blktrace data contain "C-complete" events, we can plot block IO to dm-target.
