[LARTC] conntrack event/hook when 'expected' connection terminates ?

[iler_ml at fastmail.fm]

Hello,

I need to understand how conntrack_core.c handles the termination
of 'expected' connection; handling in the case when 'expected' 
connection arrived, then terminates (In my conntrack module, 
I need to specially handle the event of termination termination 
of 'expected' connection.)

In ip_conntrack_core.c, I can't find the call chain of deallocation
of 'expectation' after termination of 'expected' connection. 
Deallocation must happen somewhere, but I don't see any hooks 
related to termination of 'expected' connection.

Or maybe the termination of expected connection is not detected at all, 
but handled via expiring timer ? Can anyone confirm or correct this ?

So my question is how is termination of expected connection handled
by conntrack code. Thanks
