From 042b10d83d05174e50ee861ee3aca55fd6204324 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Wed, 6 Nov 2013 12:19:37 -0500 Subject: tracing: Remove unused function ftrace_off_permanent() In the past, ftrace_off_permanent() was called if something strange was detected. But the ftrace_bug() now handles all the anomolies that can happen with ftrace (function tracing), and there are no uses of ftrace_off_permanent(). Get rid of it.
