Subject: [PATCH 07/20] perf hists: Introduce struct he_stat
Date: Thu, 4 Oct 2012 21:49:41 +0900 [thread overview]
Message-ID: <1349354994-17853-8-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1349354994-17853-1-git-send-email-namhyung@kernel.org>
From: Namhyung Kim <namhyung.kim@lge.com>
The struct he_stat is for separating out statistics data of a hist
entry. It is required for later changes.
It's just a mechanical change and should have no functional
differences.
