+ bool "Strict user copy size checks"
+ ---help---
+ 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.
