From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnaldo Carvalho de Melo Subject: [PATCH 82/83] perf tools: Change (symbol|annotation)__calc_percent return type to void Date: Fri, 17 Nov 2017 17:16:00 -0300 Message-ID: <20171117201601.24110-83-acme@kernel.org> References: <20171117201601.24110-1-acme@kernel.org> Return-path: Received: from mail.kernel.org ([198.145.29.99]:59464 "EHLO mail.kernel.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1161839AbdKQUUn (ORCPT ); Fri, 17 Nov 2017 15:20:43 -0500 In-Reply-To: <20171117201601.24110-1-acme@kernel.org> Sender: linux-perf-users-owner@vger.kernel.org List-ID: To: Ingo Molnar Cc: linux-kernel@vger.kernel.org, linux-perf-users@vger.kernel.org, Jiri Olsa , Adrian Hunter , David Ahern , Namhyung Kim , Wang Nan , Arnaldo Carvalho de Melo From: Jiri Olsa There's no need for symbol__calc_percent and annotation__calc_percent functions to return any value, since it's always zero. Changing both function to return void.
