From 27de9b2bd996de0ca4079c42c81c85158e10145c Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 28 May 2018 16:00:29 -0300 Subject: perf evsel: Add has_callchain() helper to make code more compact/clear Its common to have the (evsel->attr.sample_type & PERF_SAMPLE_CALLCHAIN), so add an evsel__has_callchain(evsel) helper. This will actually get more uses as we check that instead of symbol_conf.use_callchain in places where that produces the same result but makes this decision to be more fine grained, per evsel.
