| 9 | Enables the display of the minimum amount of free stack which each |
| 10 | task has ever had available in the sysrq-T and sysrq-P debug output. |

| 17 | help |
| 18 | Kprobes allows you to trap at almost any kernel address and |
| 19 | execute a callback function. register_kprobe() establishes |
| 20 | a probepoint and specifies the callback. Kprobes is useful |
| 21 | for kernel debugging, non-intrusive instrumentation and testing. |
| 22 | If in doubt, say "N". |
