--- Comment #30 from Kees Cook <kees at outflux dot net> ---
The Linux kernel is seeing more and more of these warnings and it's becoming a
bit of a burden. For example:
https://lore.kernel.org/linux-hardening/20220227195918.705219-1-keescook@chromium.org

Given that this is a regression in behavior, and the kernel is not alone in
tripping over this (9 duplicate bugs reported here already), can this be given
greater priority?

Would it be possible to add an option to just disable the "constant is a NULL
pointer" logic directly?
