There is a code path starting from trace2_def_param_fl() that eventually calls current_config_scope(), and thus it needs to have "kvi" plumbed through it. Additional plumbing is also needed to get "kvi" to trace2_def_param_fl(), which gets called by two code paths: - Through tr2_cfg_cb(), which is a config callback, so it trivially receives "kvi" via the "struct config_context ctx" parameter. - Through tr2_list_env_vars_fl(), which is a high level function that lists environment variables for tracing. This has been secretly behaving like git_config_from_parameters() (in that it parses config from environment variables/the CLI), but does not set config source information. Teach tr2_list_env_vars_fl() to be well-behaved by using kvi_from_param(), which is used elsewhere for CLI/environment variable-based config. As a result, current_config_scope() has no more callers, so remove it. Signed-off-by: Glen Choo <chooglen@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
