Subject: [PATCH 10/24] perf config: Use new perf_config_set__init() to initialize config set
Date: Tue, 7 Jun 2016 17:04:48 -0300 [thread overview]
Message-ID: <1465329902-11069-11-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1465329902-11069-1-git-send-email-acme@kernel.org>
From: Taeung Song <treeze.taeung@gmail.com>
Instead of perf_config(), this function initializes config set by
reading various files: user config ~/.perfconfig and system config
$(sysconfdir)/perfconfig).
If there are the same config variable in both user and system config
files, user config has higher priority than system config.
