Confusion in usr/include/asm-generic/fcntl.h

[Jaswinder Singh Rajput]

usr/include/asm-generic/fcntl.h is giving 2 'make headers_check' warnings:
 usr/include/asm-generic/fcntl.h:127: leaks CONFIG_64BIT to userspace where it is not valid
 usr/include/asm-generic/fcntl.h:149: leaks CONFIG_64BIT to userspace where it is not valid

usr/include/asm-generic/fcntl.h:
--
#ifndef CONFIG_64BIT

#ifndef F_GETLK64
#define F_GETLK64       12      /*  using 'struct flock64' */
#define F_SETLK64       13
#define F_SETLKW64      14
#endif

#ifndef HAVE_ARCH_STRUCT_FLOCK64
#ifndef __ARCH_FLOCK64_PAD
#define __ARCH_FLOCK64_PAD
#endif

struct flock64 {
        short  l_type;
        short  l_whence;
        loff_t l_start;
        loff_t l_len;
        pid_t  l_pid;
        __ARCH_FLOCK64_PAD
};
#endif
#endif /* !CONFIG_64BIT */

#ifndef CONFIG_64BIT will always be true for userspace. So what is the use of #ifndef CONFIG_64BIT ?

Thanks,
