See http://www.infradead.org/rpr.html Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org From: Namhyung Kim Add nr_hierarchy_entries field to keep current number of (unfolded) hist entries. And the hist_entry->nr_rows carries number of direct children. But in the hierarchy mode, entry can have grand children and callchains. So update the number properly using hierarchy_count_rows() when toggling the folded state (by pressing ENTER key).
