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.
