Source: openafs Version: 1.8.2-1+deb10u1 Severity: grave Tags: patch upstream
The openafs modules fail to build, with the compiler reporting that "stdarg.h" is not found. This is due to an intentional change in Linux 5.16 removing user-space headers from the kernel include path: <https://git.kernel.org/linus/04e85bbf71c9072dcf0ad9a7150495d72461105c>. Kernel code must use <linux/stdarg.h> instead of <stdarg.h>. The attached patch fixes this and allows the build to complete.
