From 54430101d2af260dba2d129cc9d9b7c7e60087b0 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 25 Feb 2016 00:13:37 +0900 Subject: perf hists: Introduce hist_entry__filter() The hist_entry__filter() function is to filter hist entries using sort key related info. This is needed to support hierarchy mode since each hist entry will be associated with a hpp fmt which has a sort key. So each entry should compare to only matching type of filters. To do that, add the ->se_filter callback field to struct sort_entry. This callback takes 'type' argument which determines whether it's matching sort key or not. It returns -1 for non-matching type, 0 for filtered entry and 1 for not filtered entries.
