As EEH event handling progresses, a cumulative result of type pci_ers_result is built up by (some of) the eeh_report_*() functions using either: if (rc == PCI_ERS_RESULT_NEED_RESET) *res = rc; if (*res == PCI_ERS_RESULT_NONE) *res = rc; or: if ((*res == PCI_ERS_RESULT_NONE) || (*res == PCI_ERS_RESULT_RECOVERED)) *res = rc; if (*res == PCI_ERS_RESULT_DISCONNECT && rc == PCI_ERS_RESULT_NEED_RESET) *res = rc; (Where *res is the accumulator.) However, the intent is not immediately clear and the result in some situations is order dependent. Address this by assigning a priority to each result value, and always merging to the highest priority. This renders the intent clear, and provides a stable value for all orderings.
