| Subject: linux/init.h: include <linux/build_bug.h> and <linux/stringify.h> |
| Date: Sun, 13 Nov 2022 20:08:02 +0900 |
| |
| With CONFIG_HAVE_ARCH_PREL32_RELOCATIONS=y, the following code fails to |
| build: |
| |
| ---------------->8---------------- |
| #include <linux/init.h> |
| |
| int foo(void) { return 0; } |
| core_initcall(foo); |
| ---------------->8---------------- |
| |
| Include <linux/build_bug.h> for static_assert() and <linux/stringify.h> |
| for __stringify(). |
