| 9 | Kprobes allows you to trap at almost any kernel address and |
| 10 | execute a callback function. register_kprobe() establishes |
| 11 | a probepoint and specifies the callback. Kprobes is useful |
| 12 | for kernel debugging, non-intrusive instrumentation and testing. |
| 13 | If in doubt, say "N". |
