After a quick audit of iscsi_session->lock usage, and I see that iscsi_complete_pdu(), iscsi_tmf_timedout(), iscsi_eh_cmd_timed_out(), iscsi_check_transport_timeouts() are using spin_lock(), and iscsi_session_failure() and iscsi_conn_failure() are using spin_lock_irqsave(). Mike and Hannes, would you guys mind commenting on this..? From what I can determine these should all be converted to use spin_lock_bh(), yes..?
Yeah, they can use _bh locking. I was going to use them for qla4xxx eh, which does iscsi processing in its irq, but we never did.
