From 0b5d6ece5e6a8b45c4ebbaaf831675b5b605850f Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 29 May 2018 13:28:24 -0300 Subject: [PATCH] perf hists: Introduce hist_entry__has_callchain() method We'll use this helper more frequently when reworking symbol_conf.use_callchain logic, where knowing if a hist_entry has callchains is the important bit, so make going from hist_entry to hists to evsel easier, compact.
