Subject: [PATCH 03/16] perf hists browser: Get rid of unused 'remaining' variable
Date: Fri, 22 Aug 2014 13:29:15 -0300	[thread overview]
Message-ID: <1408724968-3441-4-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1408724968-3441-1-git-send-email-acme@kernel.org>

From: Namhyung Kim <namhyung@kernel.org>

It seems that the 'remaining' variable is not used by any real code.
