Subject: [PATCH 16/22] perf hists: Fix width computation for srcline sort entry
Date: Tue, 20 Sep 2016 17:03:36 -0300 [thread overview]
Message-ID: <1474401822-18902-17-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1474401822-18902-1-git-send-email-acme@kernel.org>
From: Jiri Olsa <jolsa@kernel.org>
Adding header size to width computation for srcline sort entry,
because it's possible to get empty data with ':0' which set width
of 2 which is lower than width needed to display column header.
