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.
Thanks for the clarification. I would be happy to submit a patch next
week for this seperately from the host_lock-less conversion pieces, or
would you prefer handle this yourself..?
I am testing something now. Do not worry about it. Thanks for the work
on this.
