Tsirkin <m...@redhat.com> > Signed-off-by: Jason Wang <jasow...@redhat.com> If you perform some of the copy successfully, you have to report that length rather than just an error. Otherwise userland has no way to determine how much of the data was successfully sourced. I'm not applying this, sorry. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
