From c4dc775f53136cd6af8f88bce67cce9b42751768 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 14 Oct 2009 15:43:44 -0400 Subject: [PATCH] perf tools: Remove all char * typecasts and use const in prototype The (char *) for all the static strings was a fix for the symptom and not the disease. The real issue was that the function prototypes needed to be declared "const char *".
