Lu Baolu 861f96a785 iommufd: Remove IOMMUFD_PAGE_RESP_FAILURE ... The response code of IOMMUFD_PAGE_RESP_FAILURE was defined to be equivalent to the "Response Failure" in PCI spec, section 10.4.2.1. This response code indicates that one or more pages within the associated request group have encountered or caused an unrecoverable error. Therefore, this response disables the PRI at the function. Modern I/O virtualization technologies, like SR-IOV, share PRI among the assignable device units. Therefore, a response failure on one unit might cause I/O failure on other units. Remove this response code so that user space can only respond with SUCCESS or INVALID. The VMM is recommended to emulate a failure response as a PRI reset, or PRI disable and changing to a non-PRI domain.
