BLK_MQ_F_SET_TAGS?
I like the name

Quite a few HBAs(such as HPSA, megaraid, mpt3sas, ..) support multiple
reply queues, but tags is often HBA wide.
These HBAs have switched to use pci_alloc_irq_vectors(PCI_IRQ_AFFINITY)
for automatic affinity assignment.
Now 84676c1f21e8ff5(genirq/affinity: assign vectors to all possible CPUs)
