Subject: [PATCH v7 7/7] perf config: Reimplement show_config() using perf_config()
Date: Tue,  7 Jun 2016 18:26:17 +0900	[thread overview]
Message-ID: <1465291577-20973-8-git-send-email-treeze.taeung@gmail.com> (raw)
In-Reply-To: <1465291577-20973-1-git-send-email-treeze.taeung@gmail.com>

Old show_config() directly use config set so
there are many duplicated code with perf_config_set__iter().

So reimplement show_config() using perf_config() that use
perf_config_set__iter() with config set that already
contains all configs.
