ENOSPC if the reason it failed was because there was no more space left, and
EIO if its someother reason methinks. I reckon ENOSPC only makes sense for
drivers which handle storage media. But thats just from looking at the errno
manpage and thinking about what id expect back, im probably all wrong.
