From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnaldo Carvalho de Melo Subject: [PATCH 20/44] perf annotate: Switch struct annotation_data::percent to array Date: Thu, 9 Aug 2018 11:57:58 -0300 Message-ID: <20180809145822.21391-21-acme@kernel.org> References: <20180809145822.21391-1-acme@kernel.org> Return-path: In-Reply-To: <20180809145822.21391-1-acme@kernel.org> Sender: linux-kernel-owner@vger.kernel.org To: Ingo Molnar Cc: Clark Williams , linux-kernel@vger.kernel.org, linux-perf-users@vger.kernel.org, Jiri Olsa , Alexander Shishkin , David Ahern , Namhyung Kim , Peter Zijlstra , Stephane Eranian , Arnaldo Carvalho de Melo List-Id: linux-perf-users.vger.kernel.org From: Jiri Olsa So we can hold multiple percent values for annotation line. The first member of this array is current local hits percent value (PERCENT_HITS_LOCAL index), so no functional change is expected. Adding annotation_data__percent function to return requested percent value from struct annotation_data.
