From: "Steven Rostedt (Red Hat)" There was a time where the function tracing would disable interrupts unless specifically told not to, where it would only disable preemption. With the new lockless code, the function tracing never disalbes interrupts and just uses disabling of preemption. Remove the option "ftrace_preempt" as it does nothing anyway.
