Drivers often do that sort of thing. I don't like it personally -
ENOSPC means "No space left on device". IOW, "your disk is full".
Co-opting that code just because something kinda-sorta-similar happened
seems abusive to me. Plus the first thing poor old user is going to do
is run `df' and ask wtf?
So what's left? EINVAL is a sort of generic something-went-wrong error
code (in Linux, at least). But perhaps EBUSY ("Device or resource
busy") is suitable here.
Dunno, hard.
