Could this be MFC to 2.4, thanks.
Just cherry-picking works here.
ENOSPC isn't the most obvious error code:
when testing I first thought something wasn't right,
as 'No space left on device' isn't correct.
What about EDEADLK?
(could match the stall I had before this commit (issue1552))
It seems we don't have error message just saying 'resource shortage'.
