[PATCH 1/4] perf config: Introduce default_config_item for all default config key-value pairs

Show key headers only | View raw

We currently use values of actual type(int, bool, char *, etc.)
when initializing default perf config values.

But I suggest using new config arrays(default_config_items)
that have all default perf config key-value pairs.

Because if we do, we can manage default perf config values at one spot (like util/config.c)
and it can be easy and simple to modify default config values or add new configs.

In the near future, this could be used when
showing all configs with default values,
initializing default values of each actual config variable
with the default_config_item arrays and etc.
