Andrey Ryabinin 3ca17b1f36 lib/ubsan: remove null-pointer checks ... With gcc-8 fsanitize=null become very noisy. GCC started to complain about things like &a->b, where 'a' is NULL pointer. There is no NULL dereference, we just calculate address to struct member. It's technically undefined behavior so UBSAN is correct to report it. But as long as there is no real NULL-dereference, I think, we should be fine. -fno-delete-null-pointer-checks compiler flag should protect us from any consequences. So let's just no use -fsanitize=null as it's not useful for us. If there is a real NULL-deref we will see crash. Even if userspace mapped something at NULL (root can do this), with things like SMAP should catch the issue.
