internal / external include files

[Konstantin Andreev]

Hi, Martin.

The [$KERNEL_ROOT/include/uapi/linux/stddef.h] you are talking about is just a few lines:

| #include <linux/compiler_types.h>
|
| #ifndef __always_inline
| #define __always_inline inline
| #endif

it turns into

| #ifndef __always_inline
| #define __always_inline inline
| #endif

after [make headers_install] installs it into [/usr/include/linux/stddef.h].

Userspace applications shall not use kernel tree directly.

Regards, Konstantin.
