CONFIG_KPROBE_EVENTS_ON_NOTRACE: Do NOT protect notrace function from kprobe events

General informations

The Linux kernel configuration item CONFIG_KPROBE_EVENTS_ON_NOTRACE:

Help text

This is only for the developers who want to debug ftrace itself using kprobe events.

If kprobes can use ftrace instead of breakpoint, ftrace related functions are protected from kprobe-events to prevent an infinit recursion or any unexpected execution path which leads to a kernel crash.

This option disables such protection and allows you to put kprobe events on ftrace functions for debugging ftrace by itself. Note that this might let you shoot yourself in the foot.

If unsure, say N.
