Subject: [PATCH 1/2] perf report: Use timestamp__scnprintf_nsec for time sort key
Date: Fri, 23 Aug 2019 14:03:37 -0700	[thread overview]
Message-ID: <20190823210338.12360-1-andi@firstfloor.org> (raw)

From: Andi Kleen <ak@linux.intel.com>

Use timestamp__scnprintf_nsec to print nanoseconds for the time
sort key, instead of open coding.
