From a1d0ce8213e9ddf4046ef5ba95c55762d075f541 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Tue, 8 Jun 2010 11:22:06 -0400 Subject: tracing: Use class->reg() for all registering of events Because kprobes and syscalls need special processing to register events, the class->reg() method was created to handle the differences. But instead of creating a default ->reg for perf and ftrace events, the code was scattered with: if (class->reg) class->reg(); else default_reg(); This is messy and can also lead to bugs. This patch cleans up this code and creates a default reg() entry for the events allowing for the code to directly call the class->reg() without the condition.
