Subject: [PATCH RFC v3 10/12] perf metricgroup: Split up metricgroup__print()
Date: Thu, 7 May 2020 19:57:49 +0800	[thread overview]
Message-ID: <1588852671-61996-11-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1588852671-61996-1-git-send-email-john.garry@huawei.com>

To aid supporting system event metric groups, break up the function
metricgroup__print() into a part which iterates metrics and a part
which actually "prints" the metric.
