This will free previously allocated MSI irq vectors. 2) pcitest -i 1 /* change to MSI irq type */ This will not invoke pci_endpoint_test_alloc_irq_vectors() and pci_endpoint_test_request_irq() since now "if (irq_type == req_irq_type)" will return true. After this MSI tests will fail. Other than this failing sequence, the series looks good to me.
