You mean we could treat positive numbers returned by architecture as failures and translate it into negative error codes? If so, I would prefer not to do this for two reasons: 1. It will not be possible to call pci_enable_msi_block_part() in a loop. Although there are no consumers right now I think the very possibility is better to keep. 2. The semantics of pci_enable_msi_block_part() is very close to pci_enable_msi_block(). I believe having a consisting interface for these two helps readability. > Thanks. > > -- > tejun -- Regards, Alexander Gordeev agordeev@xxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
