And in include/asm-sparc64/fcntl.h, we have

struct flock {
        short l_type;
        short l_whence;
        off_t l_start;
        off_t l_len;
        pid_t l_pid;
        short __unused;
};
...
#ifdef __KERNEL__
#define flock64 flock
#endif

This definition for flock64 was also introduced in the test7-patch.
I reused it for the ia64-architecture fcntl.h in my patch.
On a 64 bit plattform there most probably are alignment problems with the
struct.
