system-wide debugging, and testing. This option alone does not add any

kernel code.

If you say N, all options in this submenu will be skipped and

disabled. If you're trying to debug the kernel itself, go see the

Kernel Hacking menu.

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".
