<Blush> Oops, I got used to seeing everything in /usr/src. </Blush>

But while grepping in /usr/include does produce an interface for bind(), it 
doesn't help find the implementation...

Any generic bind() would do.  I chose ipv4.

I did a lot of grepping under /usr/src for things like that, and I also did a 
lot of hand searching under /usr/src/linux/net/.  But in trying to cope with all 
the info, I must have missed the significance of the

                sock->ops = &inet_stream_ops;

assignment in the inet_create() part of /usr/src/linux/net/ipv4/af_inet.c.  In 
the same fashion as your inet_dgram_ops example, the inet_stream_ops structure 
turns out to contain inet_bind() in place of (bind*).  And as you said, 
inet_bind() is defined in af_inet.c.  Implementation found.  Thanks!
