From f4c8bae1920c459b7b9c12363d11e8a588862e42 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 28 Nov 2012 14:52:41 +0100 Subject: perf diff: Change formula methods to work with pair directly Changing formula methods to operate over hist entry and its pair directly. This makes the code more obvious and readable, instead of all time checking for pair being != NULL.
