Enabling this option turns a certain set of sanity checks for user | |
copy operations into compile time warnings. | |
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. | |
