| 13 | Enables the display of the minimum amount of free stack which each | |

| 16 | This option will slow down process creation somewhat. | |

| 40 | Enabling this option turns a certain set of sanity checks for user | |
| 41 | copy operations into compile time failures. | |
| 42 | ||
| 43 | The copy_from_user() etc checks are there to help test if there | |
| 44 | are sufficient security checks on the length argument of | |
| 45 | the copy operation, by having gcc prove that the argument is | |
| 46 | within bounds. | |
| 47 | ||
| 48 | If unsure, or if you run an older (pre 4.4) gcc, say N. | |
