From f1c67db7e351bf9fd328e368ba045cbeca11d513 Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Fri, 10 Feb 2012 15:41:56 +0100 Subject: [PATCH] perf tools: Factor out feature op to process header sections There is individual code for each feature to process header sections. Adding a function pointer .process to struct feature_ops for keeping the implementation in separate functions. Code to process header sections is now a generic function.
