Subject: [PATCH 14/45] perf tools: Add stat round event synthesize function
Date: Wed, 30 Sep 2015 16:10:27 +0200 [thread overview]
Message-ID: <1443622258-17158-15-git-send-email-jolsa@kernel.org> (raw)
In-Reply-To: <1443622258-17158-1-git-send-email-jolsa@kernel.org>
Introduce perf_event__synthesize_stat_round function to
synthesize 'struct stat_round_event'.
