FYI, I'm working on a series of minor fixups based on Andrew's comments
which I should get out early next week, probably Tuesday.
Apart from some discussion about which error codes should be returned
in certain situations, all the changes discussed so far will be
non-functional.
Except for adding a couple of #defines to the UAPI headers, there's no
other ABI impact so far.
Thanks to Andrew for his review efforts...
Cheers
