| Say Y here to get to see options related to performance measurement, | |
| 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". | |

| Place an empty function call at each marker site. Can be | |
| dynamically changed for a probe function. | |
