Sorry, I don't follow. KOBJ_ONLINE event is not emitted in the event of
xenvif_alloc fails, is it?

This patch not only implements propagation of error code when xenvif
creation fails, but also when xenbus_scanf fails. You can simply write
"This patch implements propagation of error code for
backend_create_xenvif".

The rest of this patch looks good to me. Can you rewrite commit message
and resubmit, thanks.

Wei.
