I had to change this a bit since the context for the patch was
modfified, it's now
for (function = 0; function < QEMU_PCI_ADDRESS_LAST_FUNCTION; function++) {
if (function == 1 && (reservedIDE || reservedUSB))
/* we have reserved this pci address */
continue;
if (qemuDomainPCIAddressReserveFunction(addrs, 1, function) < 0)
goto error;
}
please double check :-)
I will let you address Wen comments separately !
