After a quick audit of iscsi_session->lock usage, and I see that

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.
