From 13d1e536b14ec2d404319a25e681a3287ca084ad Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Sun, 21 Jun 2015 12:41:16 +0900 Subject: [PATCH] perf top: Move toggling event logic into hists browser Current 'f' key action to enable/disable events won't work if there're more than one event since perf_evsel_menu__run() doesn't return the key. So move it to the hists browser loop so that it can be processed as like other key action, and it's more natural to handle it there IMHO.
