Subject: [PATCH 11/13] perf tools: Add ->sort() member to struct sort_entry
Date: Thu, 20 Mar 2014 10:31:25 +0900 [thread overview]
Message-ID: <1395279087-12554-12-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1395279087-12554-1-git-send-email-namhyung@kernel.org>
Currently, what the sort_entry does is just identifying hist entries
so that they can be grouped properly. However, with -F option
support, it indeed needs to sort entries appropriately to be shown to
users. So add ->sort() member to do it.
