Say Y here to enable the extended profiling support mechanisms used by profilers such as OProfile.
OProfile system profiling
OProfile is a profiling system capable of profiling the whole system, include the kernel, kernel modules, libraries, and applications.
If unsure, say N.
Если не уверены, выбирайте N.

Kprobes 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.
Если сомневаетесь, скажите N.
