From: Arnaldo Carvalho de Melo
Date: Wed Feb 03 2016 - 11:36:46 EST


See http://www.infradead.org/rpr.html

From: Jiri Olsa <jolsa@xxxxxxxxxx>

Separating output fields parsing into setup_output_list function, so
it's separated from field_order string setup and could be reused later
in following patches.
