--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So, instead (when building the kernel with sanitization) build with
-fsanitize=signed-integer-overflow and no -fno-strict-overflow, and
the routines where you want wrapv behavior and not runtime traps build with
optimize ("wrapv", "wrapv-pointer") attribute?
