From 599a2f38a989a79df99838f22cb607f5e2b5b56c Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Wed, 9 Mar 2016 23:20:53 +0900 Subject: perf hists browser: Check sort keys before hot key actions The context menu in TUI hists browser checks corresponding sort keys when creating the menu item. But hotkey actions lacks these checks so it can filter using incorrect info. For example, default sort key of 'perf top' doesn't contain 'comm' or 'pid' sort key so each hist entry's thread info is not reliable. Thus it should prohibit using thread filter on 't' key.
