From 3186b6815d49b5e0defbd884223da3778edb59fc Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 22 Apr 2014 13:44:23 +0900 Subject: [PATCH] perf hists: Add missing update on filtered stats in hists__decay_entries() When a filter is used for perf top, its hists->nr_non_filtered_entries was not updated after it removed an entry in hists__decay_entries(). Also hists->stats.total_non_filtered_period was missed too.
