help
Compiles the kernel with KPROBES support, which allows you to trap
at almost any kernel address and execute a callback function.
register_kprobe() establishes a probepoint and specifies the
callback. Kprobes is useful for kernel debugging, non-intrusive
instrumentation and testing.
If in doubt, say "N".
