Thanks, that's what I expected. While this is not possible, the only requests I have for this patch is that we clearly document: * What's the only purpose of share=on on a host-memory-backend object (due to pvrdma limitations). * The potential undesirable side-effects of setting share=on. * On the commit message and other comments, clearly distinguish HVAs in the QEMU address-space from IOVAs, to avoid confusion. -- Eduardo
