[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


* src/node_device/node_device_driver.c (nodeNumOfDevices)
(nodeListDevices, nodeDeviceGetXMLDesc, nodeDeviceCreateXML):
Reject unknown flags.
* src/node_device/node_device_hal.c (halNodeDrvOpen): Likewise.
* src/node_device/node_device_udev.c (udevNodeDrvOpen): Likewise.
