cannot reach xfs_ioctl

[Naomaru Itoi]

Hi.

I am trying to implement ioctl function in arla.  I wrote some code in
xfs_vnodeops.c : xfs_ioctl().  But the function does not seem to be
called when I call ioctl() system call.  

rv = ioctl(fd, 1, buf_io);

fd is an opened file descriptor on arla file.  
ioctl() returns with errno=25 (NOTTY).  

Any ideas?

Thanks.
