Hi Oleksandr, PVCalls is a bit different, because the protocol is meant to send POSIX calls to the backend, therefore, I have to use POSIX error names in the protocol. I could assign any numbers to the names though. It makes sense to use the Xen/Linux error numbers for simplicity. Whether I declare them directly as numbers as I have done here, or indirectly as XEN_ERRNO, I don't think it matters much. But I think that using numbers is clearer, that's why I did it that way. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
