![]() It is possible for the target code to change the loop_id or s_id of a target session in reaction to an FC fabric change. However, the session structures are stored in tables that are indexed by these two keys, and if we just change the session structure but leave the pointers to it in the old places in the table, havoc can ensue. For example, a new session might come along that should go in the old slot in the table and overwrite the old session pointer. To handle this, add a new tgt_ops->update_sess() method that also updates the "by loop_id" and "by s_id" lookup tables when a session changes, so that the keys where a session pointer is stored in these tables always matches the keys in the session structure itself.
