From 9283ba9bd77a6940ecad8721429131d773c704b8 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 24 Apr 2014 16:37:26 +0900 Subject: [PATCH] perf hists: Add a couple of hists stat helper functions Add hists__{reset,inc}_[filter_]stats() functions to cleanup accesses to hist stats (for output). Note that number of samples in the stat is not handled here since it belongs to the input stage.
