It might have been good to call attention to the fact that
you were fixing it so ioend->io_error is consistently a
negative errno value now, thereby making the above change
possible.

Are we going to drop the last argument to aio_complete() now?

Anyway, this looks good, and as you privately requested
I will commit this patch without waiting for resolution
of issues in the other two in this series.
