This is not a good way to do it. See e.g. fs/pipe.c#read_fifo_fops
for an easier approach:

struct file_operations read_fifo_fops = {
        llseek: no_llseek,
        read: pipe_read,
        write: bad_pipe_w,
        poll: fifo_poll,
        ioctl: pipe_ioctl,
        open: pipe_read_open,
        release: pipe_read_release,
};
