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