12 | Enabling this option turns a certain set of sanity checks for user | |
13 | copy operations into compile time warnings. | |
14 | ||
15 | The copy_from_user() etc checks are there to help test if there | |
16 | are sufficient security checks on the length argument of | |
17 | the copy operation, by having gcc prove that the argument is | |
18 | within bounds. | |
19 | ||
20 | If unsure, or if you run an older (pre 4.4) gcc, say N. | |
