This way we'll be able to pass more test specific parameters without having to change this function signature. Will be used by the upcoming 'shell tests', shell scripts that will call perf tools and check if they work as expected, comparing its effects on the system (think 'perf probe foo') the output produced, etc. Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Thomas Richter <tmricht@linux.vnet.ibm.com> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-wq250w7j1opbzyiynozuajbl@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
