From d5dbc518cd8fbc7cf54b91d5b506eb4d67e4047d Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 17 Mar 2015 18:27:28 -0300 Subject: [PATCH] perf hists browser: Allow annotating entries in callchains Instead of annotating just the top level hist_entry, allow instead annotating a map_symbol, i.e. the top level hist_entry or one of the callchains for which there were samples.
