Hmm, but I'm still a bit confused. For a module close (which is what is
happening here), ip_quiesce_conn() doesn't get called. In ip_close():
/*
* Call the appropriate delete routine depending on whether this is
* a module or device.
*/
if (WR(q)->q_next != NULL) {
/* This is a module close */
return (ip_modclose((ill_t *)q->q_ptr));
}
connp = q->q_ptr;
ip_quiesce_conn(connp);
For the ip_modclose() case, something other than ip_quiesce_conn() has
to clean up the ilm's. I'm guessing something in ill_delete() must do
this.
