I could also add back concurrent enqueue support for mergeable RX, but I
was hoping to avoid that since the mergeable codepath is already complex
and wouldn't be used in high performance deployments.

Another note is that, you might also have noticed, Zhihong made a patch
set [0] to optimize the enqueue code path (mainly on mergeable path). It
basically does a rewrite from scatch, which removes the desc buf
reservation,
meaning it would be harder to do concurrent enqueue support based on that.

Yes, I'd noticed that these patches would conflict. Once the vhost-cuse
removal and
Zhihong's patches have merged I'll send a new version.

What is the status of this feature?
