Mpool points out places where the existing apis fail to scale. Rather than attempt to fix that problem it proposes to replace the old apis. However, the old apis are still there. So now upstream has 2 maintenance burdens when it could have just had one. So when I ask "what does Linux get" it is in reference to the fact that Linux gets a compounded maintenance problem and whether the benefits of mpool outweigh that burden. Historically Linux has been able to evolve to meet the scaling requirements of new applications, so I am asking whether you have tried to solve the application problem by evolving rather than replacing existing infrastructure? The justification to replace rather than evolve is high because that's how core Linux stays relevant.
