:Now that I'm back in town and had a chance to look at fcntl() again, I agree
:that this is a better approach.  The syscall does copyin/copyout's only on
:a struct flock.  Thus, I think kern_fcntl() will be prototyped as:
:int kern_fcntl(int fd, int cmd, struct flock *fl);
:For any cmd that doesn't take a struct flock, I'll just pass a null pointer.
:The ioctl() syscall will be an entirely different story.

    Allright, sounds good.
