We only include linux/kdbus.h. On sanitized headers, this will include linux/types.h -> linux/posix_types.h -> linux/stddef.h. If you use the uapi headers, then stddef.h is not sanitized and will still include linux/compiler.h (which is removed on sanitized headers). Hence, this error only occurs if you include uapi/linux/kdbus.h. With sanitized headers in ./usr/, the compiler will prefer ./usr/linux/kdbus.h and ./usr/linux/stddef.h, thus never including any linux/compiler.h. If you drop -I./include/uapi/, you will get "linux/kdbus.h not found". The error will be different, but it will not fix anything. However, if you run "make headers_install", everything will compile just fine even with -I./include/uapi/.
