I'm wondering if we are better served by turning this into generic logic in kernel/workqueue.c to be used beyond qla2xxx, or: using WQ_UNBOUND (following iser-target) and verify if observed bottleneck is due to internal !(WQ_UNBOUND) usage in qla_target.c. Out of curiosity, what level of performance improvement does this patch (as is) actually provide..?
