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.
12 This option will slow down process creation somewhat.

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.

41 This results in a large slowdown, but helps to find certain types
42 of memory corruptions.
