From c611152373e84a7677cd7d496e849de4debdab66 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 7 Oct 2016 14:04:12 +0900 Subject: perf top: Fix refreshing hierarchy entries on TUI Markus reported that 'perf top --hierarchy' cannot scroll down after refresh. This was because the number of entries are not updated when hierarchy is enabled. Unlike normal report view, hierarchy mode needs to keep its own entry count since it can have non-leaf entries which can expand/collapse.
