From: Arnaldo Carvalho de Melo
Date: Wed Nov 23 2016 - 11:42:04 EST


From: Jiri Olsa <jolsa@xxxxxxxxxx>

Adding -f/--force option to go through ownership validation:

$ sudo perf c2c report
File perf.data not owned by current user or root (use -f to override)
$
$ sudo perf c2c report -f
< c2c report output >
$
