| 417 | Kprobes allows you to trap at almost any kernel address and |
| 418 | execute a callback function. register_kprobe() establishes |
| 419 | a probepoint and specifies the callback. Kprobes is useful |
| 420 | for kernel debugging, non-intrusive instrumentation and testing. |
| 421 | If in doubt, say "N". |
