Dear all, is it correct that the files under include/uapi/ can be included by a user space application? I just ran into an error where my application ended up including include/uapi/linux/stddef.h (with a number of intermediate steps). This fails because the kernel's stddef.h includes include/linux/compiler_types.h and this file is internal to the kernel. What is the correct way to solve this? Should I fix my include path to make sure that my application picks the stddef.h in the compiler's sysroot rather than the kernel's stddef.h? Or should include/uapi/linux/stddef.h guard the kernel-internal parts using #ifdef __KERNEL__? Thanks, Martin
