Subject: [PATCH v3 05/11] perf util: Create the runtime_stat init/free function
Date: Wed, 29 Nov 2017 20:05:52 +0800 [thread overview]
Message-ID: <1511957158-5813-6-git-send-email-yao.jin@linux.intel.com> (raw)
In-Reply-To: <1511957158-5813-1-git-send-email-yao.jin@linux.intel.com>
It mainly initializes the rblist in struct runtime_stat.
For the original rblist 'runtime_saved_values', it's still there
for keeping the patch bisectable. The rblist 'runtime_saved_values'
will be removed in later patch at switching time.
Signed-off-by: Jin Yao <yao.jin@linux.intel.com>
