From 82151520938ec79e5e3adb7e61977f002031c38c Mon Sep 17 00:00:00 2001 From: Cody P Schafer Date: Fri, 10 Aug 2012 15:22:48 -0700 Subject: perf symbols: Remove unused 'end' arg in kallsyms parse cb kallsyms__parse() takes a callback that is called on every discovered symbol. As /proc/kallsyms does not supply symbol sizes, the callback was simply called with end=start, faking the symbol size to 1. All of the callbacks (there are 2) used in calls to kallsyms__parse() are _only_ used as callbacks for kallsyms__parse(). Given that kallsyms__parse() lacks real information about what end/length should be, don't make up a length in kallsyms__parse(). Instead have the callbacks handle guessing the length. Also relocate a comment regarding symbol creation to the callback which does symbol creation (kallsyms__parse() is not in general used to create symbols).
