[PATCH 2/3] perf config: Rework buildid_dir_command_config to perf_buildid_config

Show all headers | View raw

To avoid repeated calling perf_config()
remove buildid_dir_command_config() and
add new perf_buildid_config into perf_default_config.

Because perf_config() is already called
with perf_default_config at main().
