if WAIT_FOR_SUBMIT isn't set and in the meanwhile no underlying fence on syncobj, then return non-block error code to user sapce.
Block device required?
Yes, if WAIT_FOR_SUBMIT is set, then that will block device.
No, the error message is that it requires a "block device", not that it will block the device, which is EWOULDBLOCK.
OK, I got your mean.
Any other possile value suggestted?
