| 37 | Enabling this option turns a certain set of sanity checks for user |
| 38 | copy operations into compile time failures. |
| 39 | |
| 40 | The copy_from_user() etc checks are there to help test if there |
| 41 | are sufficient security checks on the length argument of |
| 42 | the copy operation, by having gcc prove that the argument is |
| 43 | within bounds. |
| 44 | |
| 45 | If unsure, or if you run an older (pre 4.4) gcc, say N. |
