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. | |

16 | depends on DEBUG_KERNEL | |
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". | |

40 | Unmap pages from the kernel linear mapping after free_pages(). | |
41 | This results in a large slowdown, but helps to find certain types | |
42 | of memory corruptions. | |
