Setting that flag in hisi_sas_v2_interrupt_preinit() might be best. Thanks, John
Only megaraid_sas actually ever uses more than a single blk-mq queue, so this looks weird?

Set shost->use_managed_irq if irq vectors are allocated via pci_alloc_irq_vectors_affinity(PCI_IRQ_AFFINITY) or pci_alloc_irq_vectors(PCI_IRQ_AFFINITY). The rule is that driver has to tell scsi core if managed irq is used.
