Help text

Functions will have the stack-protector canary logic added if they have an 8-byte or larger character array on the stack.

This feature requires gcc version 4.2 or above, or a distribution gcc with the feature backported ("-fstack-protector").

On an x86 "defconfig" build, this feature adds canary checks to about 3% of all kernel functions, which increases kernel code size by about 0.3%.
