From 3279ba37db5d65c4ab0dcdee3b211ccb85bb563f Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 7 Oct 2009 16:57:56 -0400 Subject: ftrace: check for failure for all conversions Due to legacy code from back when the dynamic tracer used a daemon, only core kernel code was checking for failures. This is no longer the case. We must check for failures any time we perform text modifications.
