Stefan, Does this version look better ?

Looks good, thanks! Michael is the maintainer and this patch series will go through his tree. Stefan

Can we apply this now ? I have developed code for rust-vmm crates based on this and we need to get this merged/finalized first before merging those changes. Thanks.

I've queued into my virtio/vhost-user-device series so I'll get merged with that series unless mst wants to take it now. > > Thanks.

Well the patches are tagged and I was going to take these after the release. Probably easier not to work on this in two trees. Still if there's something in your tree being blocked by these patches then Acked-by: Michael S. Tsirkin <mst@redhat.com> Let me know. > > > > Thanks. > > > -- > Alex Bennée > Virtualisation Tech Lead @ Linaro

The virtio/vhost-user-device tree work is orthogonal to this vhost-user enhancement although all the work is related to our latest VirtIO project inside Linaro, Orko: https://linaro.atlassian.net/wiki/spaces/ORKO/overview So if you are happy please take these patches now for when the tree re-opens. > > >> > >> > Thanks. >> >> >> -- >> Alex Bennée >> Virtualisation Tech Lead @ Linaro
