[PATCH 26/31] perf record: Avoid duplicate call of perf_default_config()

From: Arnaldo Carvalho de Melo
Date: Tue Mar 13 2018 - 08:07:08 EST


From: Yisheng Xie <xieyisheng1@xxxxxxxxxx>

We have brought perf_default_config to the very beginning at main(), so
it no need to call perf_default_config() once more for most of config in
perf-record but only for record.call-graph.
