Petri, yesterday I rose question about switching to return codes in way 
as your patch does. Everybody liked this solution. We also do not use 
errno anywhere in code.
Unfortunately you were absent and I could not check it with you 
yesterday. From one thing we should be consistent with all other APIs 
from other returns codes in that way is very natural (like read(), 
write(), ioctl() do). From my point of view we do not break code style / 
rules here. So please confirm.

Thanks,
Maxim.
